Moving songs

I found a comment in a thread where was said that the "add selected songs to setlist copies songs instead of moving". I wanted to sort my cdlc in setlists trough the manager (while being able to see the tunings) but the copy option makes it a lot harder to actually make setlists and being sure I'm not missing any songs etc. No idea if it is still possible or too much work, but I would love a toggle option for this, where we can either chose to move or to copy a song to a setlist so the cdlc's don't just stay in the main cdlc folder after adding them to a setlist.

 

I can see the copy option being good to make multiple setlists with the same songs, but it's very hard to actually make setlists when all the songs just stay in the main list you have to use to add them to setlists.
