Naming of folder by using but changing album title

My library of concert recordings are tagged like this

Artist: "Miles Davis"
Album: "Universitetet, Uppsala - 1971-11-07"

and from this I want to change the name the folder to:

"Miles Davis - 1971-11-07 - Universitetet, Uppsala"

I have the action for naming the folder with format string like this:
%artist% - %album%

but I can't understand how to move and change places for the venue and the date...

Thanks in advance /Hank

Instead of
%artist% - %album%


%artist% - $regexp(%album%,'(.) - (.)',$2 - $1)

Thank you!
