How do you want Opus to decide on the name of the folder? i.e. The artist name.
If you mean you want to use the music tags, see #11 in Various Simple Rename Scripts. Note that only files containing music tags will be moved by that and any other files, such as jpeg cover art or m3u playlists, will be left where it is.
If you want to select some folders and then have Opus ask you to type the name of the folder to create and move them into then you can do that as well. I'm on my phone so don't have the exact command to hand but say if that is what you want.
