Configurable multi-part works in radio

Multi-part works can be very lengthy in classical music. For example an entire Opera Act, 33 Diabelli Variations etc.

I can select a single track on to my queue and I like to do that to ‘seed’ the radio. The problem is that radio will then pick lengthy multi-part music when the whole reason for me letting radio kick-in is to explore long forgotten corners of my library. If I want to play an entire work I can do that myself.

Is it possible to make radio configurable so that it can shuffle either works, parts or both?
