Select something to play after Radio

This title may be not too clear, but what I meant is this:
I am listening to Roon Radio and come across one long song by a band I like.
So I wanted to keep listening to that song until the end and cue up a random mix of all this band’s work afterwards. Seems pretty straightforward, but I can’t find how to do it.
Am I missing something or would that actually be a feature request?
