Trigger Snapper Menu - suggestion

It would great if there was an additional option "Change on Completion of Track"

I have Grooves containing tracks that span multiple measures which contain long audio samples, tracks with FXs, etc.
With the current implimentation the maximum setting is "Change on Measure. This can cause problems if, for example, I have a 4 bar groove an I advertently trigger the next groove too soon - the groove will switch at the end of the 3rd measure instead of the 4th.
