Filtering group rides by narrow W/Kg ranges

As a beginner wanting to do group rides, it seems that group “D” has a wide range of paces. The upper end of “D” is not comfortable yet. It sure would be nice to filter group rides by narrow ranges of W/Kg (for example, 1.2 to 1.5). Good idea for Zwift to think about?

This is a very specific request, I kind of doubt they will even take it into consideration, as a lot of events, for D cat specifies extra info in the event description.
Perhaps you can use Events to try to find/filter such events?
