Thanks for the reply cfillion,
Unfortunately the $regionnumber wildcard doesn't do the trick. It numbers the exported regions on a pre-track basis, starting at 1 again for each new track.
So I get johnny_1, johnny_2, johnny_3 / billy_1, billy_2, billy_3 and so on.
I'm trying to get each number to correspond to the sequence order. So if johnny speaks, then billy speaks, then johnny speaks again I would get johnny_1, billy_2, johnny_3. The numbers would be based on their chronological order on the timeline regardless of the track.
I looked at the list in "wildcard help" (thanks again for that), but none of the descriptions on the list seem to do what I'm looking for. I guess this is why I was inquiring about a custom wildcard. The $start wildcard is very close, but it's not quite there.
Anyway, I'm repeating myself.
Thanks again for the reply.
Hopefully there is an answer out there
