Local Time Signature

I posted a little bit ago but it seemed that there may have been some ai or spam type response. I was just curious if musescore has a way of using local time signatures. I'm trying to chart something out with the melody in 4/4 but the supporting instruments are in 12/8. just wondering if there is a workaround or any way to do this. I've tried to use the cmd and just drag it but it said that Musescore did not support this yet.
