Vivid user of Longplay… brilliant!

I might be overlooking something but I’m stuck with the following scenario:

In the evenings, I run a Shortcut, selecting a random album from a Longplay collection containing some easy-listening stuff before dosing off.

The next day, Longplay will still be “stuck” on this collection until you manually select the entire library again. Is there a way via the shortcuts a way to “reset” the app to consider the entire library again (besides starting to create an “all album” collection or something)? Thanks!
