How to disregard inversions in search

I want to search progressions in TheoryTab Trends but (for particular reasons) I want to treat all chord inversions as equivalent. E.g., the progressions IV - I 6/4 and IV - I would be the same (to my search). Is there a way to do this using the HookTheory search function, or do I just have to manually do different searches for all different inversions and then take the union of these results (which I have been doing, but I wonder if there is an automated way).
