That's it!
1) Select: 'auto-punch-time-selection' mode.
2) Unlink loop-points and time-selection.
3) Set time-selection to punch-in/out area
4) Set loop points to taste
And yes by default the are linked. To unlink go to OPTIONS then uncheck the "Loop points linked to time selection"
Thanks a bunch, now I can do multiple takes in punch-in situations. What a relief.
