MuseScore Polyrhythm Help? I need help changing the time signature without changing the notes. How would I do this?

I accidentally set this part up in 4/4 when but I need it to be in 6/4 (or 12/8). In MuseScore, how would I efficiently make the Viola section (the one with all the quarter notes. Have four dotted quarter notes and have the second violins, cellos, and basses (the other 3) be playing a normal rhythm (4 quarter notes, 2 eighths, and another quarter note)? I REALLY don't want to have to redo this from the ground up. Surely there is some way to fix this?

I arrange and transcribe a LOT - and just wrote a whole long response, and then erased it It is ONLY 20 bars - I just did about 720 in the past couple of weeks/month. You will learn from the process - try to save what you can, but you will have to hand-enter this how you want it. For the violas - big duplets over each dotted half in 6/4. Or write the whole thing in 4/4, and have the other string parts in big triplets over half notes. Your call - it is a matter of pulse and metric feel, which way you go with this.

in the time it took you to type this question and read this answer you could have fixed it yourself from the ground up shake my head
