Windowsform - How to add two Datagridviewbuttoncell in the same Ell?

Question

Is it possible to add two Datagridviewbuttoncell type buttons in the same cell in a Datagridview? I’ve done a lot of research and so far I haven’t been able to find any solution.

Edit 1: For example, I wanted to add a [Morning] and another [Afternoon] button on the same... I tried to add a panel, but it does not accept, because Datagridviewbuttoncell is not Control type.

Edit 2: That’s what I can do these days...

Edit 3: Well, I’ve come up with a solution for this business model. @Rovannlinhalis came up with the idea of creating an extra column so that it could divide between MORNING and AFTERNOON. The problem arises when the user chooses the BIWEEKLY or MONTHLY calendar option, as many columns would be generated... Well, instead of adding n columns, I added extra rows, which are divided between MORNING and AFTERNOON. Ex:

But I’m having some difficulties regarding the events of Windows Form. In this Datagridview I am creating a Rectangle and giving a Drawstring in it in Rowheader, for each line, where the room numbers appear (ROOM: 22). This is the solution I found because Datagridview does not have Rowspan.

Anyway, the problem appears when I select a line and then I select another one. It seems that Rectangle is invisible... Ex:

Event code:

reservaGrid_Grid.CellPainting += (sender, e) =>
        {
            if (e.ColumnIndex == -1 && e.RowIndex > -1)
            {
                //exibe as datas em cima das colunas, desenhando de duas em duas linhas
                for (int i = 0; i < reservaGrid_Grid.RowCount; i += 2)
                {
                    string quarto = string.Format( "Quarto: {0}", Funcoes.String.FindStringAfterCharacter(reservaGrid_Grid.Rows[i].Tag.ToString(), '_') );

                    Rectangle retangulo     = reservaGrid_Grid.GetCellDisplayRectangle(-1, i, false);
                    //int largura           = reservaGrid_Grid.GetCellDisplayRectangle(-1, i + 1, true).Width;
                    retangulo.X             += 1;
                    retangulo.Y             += 1;
                    retangulo.Width         = retangulo.Width / 2 + 15;//largura do header
                    retangulo.Height        = retangulo.Height;//tamanho do header, preenche 2 linhas
                    StringFormat format     = new StringFormat();
                    format.Alignment        = StringAlignment.Center;
                    format.LineAlignment    = StringAlignment.Center;

                    //pinta o fundo do retangulo
                    e.Graphics.FillRectangle(
                        new SolidBrush(
                            reservaGrid_Grid.ColumnHeadersDefaultCellStyle.BackColor
                        ),
                        retangulo
                    );

                    //desenha a string no retangulo
                    e.Graphics.DrawString(
                        quarto,
                        new Font(reservaGrid_Grid.ColumnHeadersDefaultCellStyle.Font.FontFamily, 13, FontStyle.Bold),
                        new SolidBrush(reservaGrid_Grid.ColumnHeadersDefaultCellStyle.ForeColor),
                        retangulo,
                        format
                    );
                }
            }
            //reservaGrid_Grid.Invalidate();
        };

Why will it be?
