Exporting divisi parts from a score

I have a significant amount of divisi in my piece and exporting parts has been hell for me. In the score, all the parts are supposed to to be on one staff, that's easy enough. What's been bothering me is exporting the parts since I need both the violin 1 staff for the unison parts but for the divisi parts I want it to be like the picture from La Valse. In that part, the editor just separates the div and unis sections between the rows but I cant always do that. In addition I don't know if musescore allows to hide a staff forcefully for one row or shrink the staff size for one row.

The only solution I've seen that's possible is to delete the violin 1 (full section) from the score temporarily in order for it not to appear in the parts then export the parts then put it back in the score but that sounds so backward and bad I don't even want to consider doing it. Please help me before my monitor breaks.
