Mass delete of all mods for a given game - How do I do that

[WG2107]

I need to do a mass delete of mods for Skyrim that were left when I removed a collection

Deleting the collection itself should've queried you whether you want to delete the mods and archives. I'm afraid that if you bypassed that dialog there's no way for Vortex to know which collection those mods blonged to and it's now impossible to remove them based on a certain collection.
