Filtering a dashboard view

Hello! Happy New Year!
I am trying to filter a dashboard grid view based on a moving criteria. We want to filter to current month, then +/- a few months on subsequent tabs. The problem is: I am not looking at the data in terms of calendar months. We use fiscal month/period and so I am effectively trying to write an expression (like I can do in the BAQ) to determine the current fiscal month and year and then filter by it. Can I do that in a dashboard filter? It doesn’t seem terribly obvious and I did not find any other such issues in here.

Thanks, in advance.

This appears to be a good solution. I’m going to give it a go.
