How to show on Musescore Repeat say 4th part then end with last 4 bars of 2nd part

Basically I have a 4 part tune, with 8 bars in each part, All parts are repeated fully except 4th part, which is repeated but after playing the 8 bars once, go back and play the first 4 bars of 4th part again and then jump back to play the last 4 bars of the second part instead of the last 4 bars of the 4th part.
I would normally call this 1st and 2nd time repeats and would normally show it as 1 of 4th and 2 of 4th.
To indicate the bars to play on 1st time and the bars to play on 2nd time.
I cannot get Musescore to do it...I was using voltas....the work when the 1st and 2nd endings are following each other at the end of the same part, but I cannot get it to play repeat end by jumo back on an earlier part.
