BD Mysql Sync

Question

Good morning, About Mysql data synchronization where you have the Master server and the Slave server, I would like to know if it is possible for me to have several master for a single slave, where the master would synchronize with the slave inserting data and searching for data from the other databases in the slave. I need this for the following scenario: We have several companies in different locality and each company will have its local database which should send the inserts/changes made and receive the changes from the other subsidiaries, where there would be a comic book that would be responsible for having all the information and sharing with others.
