Files from several locations on my hard drive are grouped in itunes under the grouping '001' for example. Group '001' makes up one disc of mp3s. I want to further distinguish each song in the group so I can see what track number each song is on the mp3 disc.
I could go and separately change individual song's grouping to 001-1, 001-2 but that would take about 9 years.
Can Mp3tag aid in this mission?
Thanks very much.

If the grouping is stored in a tag field you can use a Format value action for the field which can append the value of the track field to this grouping field.

Thanks Florian, I'm going to give that a try this afternoon.
