using drill through with multiple criteria selection

hi there, 
this is my first post, so forgive me. here goes. 

I have a nice tool set up but my user would like to select multiple critera before using the drill through tool. I see that there is a way to write a DAX query, but most of the query suggestions I see are for time/date options. 
This report is for fundraising prospecting, so I need to select criteria like interest unit, with a prospect rating, or unit and the last gift amount. I've got some sample/dummy data, but I don't have a great way to share it right now. 
here's just the header and first row.

thanks,
Theresa Markham
