Requiring one date prompt OR another at FM Level?

[lazrobot]

This particular FM Model has 3 dates: Invoice Date, Order Date and Delivery Date.  For performance sake, I'd like to require users specify a date range for one of these three for any given report (but not ALL three).

Is there a way to create this kind of requirement at the FM Model level?  I was thinking you could use Parameter Maps somehow, but I can't quite figure out how it would work.  I'd hate to do this over and over in Report Studio.
