Hello. Thanks for the great product. I'm reformatting my entire music collection and was wondering if there is a way to change the way the Autonumber Wizard functions.

What I'm hoping for is a way to have the track numbers read relative to how many discs there are in a set.

eg: 1-01 (Disc 1-Track01)

as opposed to the 01/12 format the Wizard currently uses.

Is this possible either through the Wizard or through Actions?

Many thanks!

Are the tracks already numbered and is the disc number contained in the DISCNUMBER field? If so, then a simple Action would do it.

_Action type:_ **Format value**  
_Field:_ **TRACK**  
_Format string:_ **$fmtNum(%discnumber%)-$num(%track%,2)**
