Is there a way to determine the order that the Transaction Groups execute?

For example, I have some transaction groups that Insert, and others that Update. While the trigger is active for the Insert groups (one scan), I don’t want the Update groups to run.

Or if they do run, at least run AFTER the Insert groups.

This is sometimes a bit hard to guarantee. I recommend using the ‘Write handshake on success’ to set the trigger for the next group.

Thanks for the reply.  
Ultimately we decided to write a custom Where clause on the Update Group to prevent this scenario from occurring.
