Query Absolute Value

Duplicate of here.

I want to query the absolute value of a param. Say I have a fixture with tilt 90, I can `Query Tilt 90` and have that fixture selected, great. But if I store that same tilt 90 value into FP 1, and `Query Tilt 90` it no longer works, I have to `Query FP 1` Is there a way to query by the absolute value of a param?
