Set file cell *.CSV as merged

Question

Is it possible for a given cell to be merged into a generated *.csv file? I ask because I am generating a *.csv file where the user should only do one Ctrl + C \ Ctrl + v in the content and paste in a standard spreadsheet, however this standard spreadsheet has the cell as merged where will be pasted this content and I can not modify this in the standard spreadsheet so for this reason the need.

import java.nio.charset.StandardCharsets;
import java.util.logging.Logger;
Logger logger= Logger.getLogger("org.bonitasoft");

logger.info(suprimentosDevolvidos.toString())

BufferedWriter strW = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("C:\\TESTE\\suprimentos.csv"), StandardCharsets.ISO_8859_1));

strW.write("QUANTIDADE TOTAL LOTE: "+quantidadeTotalLote.toString()+"\n")
strW.write(suprimentosDevolvidos.toString())
strW.close();
