Help. Pro Rate PM Commission like Rent on Owner Statement

I’m in urgent need of help figuring out how to prorate the PM commission on the owner statement, so that it aligns with how rent is split based on which nights fall within the month and which do not. I'm using the PMV2, it worked fine before update. Is there a way to call support? I've sent emails and have researched for hours, am I missing something? This is very time-sensitive.
