Please Add Track and Composition Length to Focus

I wanted to create a playlist of “short classical pieces”. I would have liked a proportion of string and keyboard cuts.

I can’t find a way to do this in Roon. What’s needed are “focusable” track and/or composition lengths, as the case may be. What else is needed is the ability to create proportional playlists.

Granted, this is a small area of a much larger need for greater playlist flexibility, but I thought I’d mention it. Thxs.
