Data grid intracolumn separator: change comma to semicolon

Hi! I have a data grid for entity A. Entity A has a many-to-many relationship to entity B. Entity B has attribute B1 (a string). In the data grid for entity A I want to have a column showing attribute B1. Because this is a many-to-many relationship, per row there will be more than one B1 value in that column. By default the separator used is the comma. Is there an easy way (a setting somewhere) to change this comma to a semicolon? Or do I have to build a microflow to create the desired concatenated string?

I would go for the concatenated string because I do not think you can change the character.
