I'm wondering if it is possible to save the one song in two different keys/transpositions in two different playlists?

I have quite a few songs that I play in different bands in different keys, so I was hoping to be able to save a playlist for each band with the song in the key they play it in. At the moment if I transpose a song for one play list it alters the song for each play list that the song is in, not just the song in the list it is in.

The way around it I have found is to edit and save each song under a different name/band and key but this means that for each song there is 2-4 copies of each, which is very, very messy and seems unnecessary.

Is there a way to do this??

Cheers!
