Filter "Active" Shapekeys

I’m wondering if there’s a way to filter for Shapekeys that have a non-zero value? If not, where can I make such a feature request?

I’m working with character models that have several hundred shapekeys for facial expressions. It becomes pretty difficult to track which shapekey is actively used or not without scrolling through the entire list every time. Having the ability to toggle just the “active” shapekeys would make working with shapekeys indefinitely better.

Thank you
