With this mod you're able to create playlists from Workshop Collection links!
In any level select menu, there will be an extra option below the available campaigns called "Add Playlist".
When you select that option you will be prompted to "Enter Playlist Link".
Paste a Steam Workshop Collection link there.
This will be a playlist from the collection entered into the prompt.
Any levels that do not match the mode you are making a playlist for will be filtered out.
