As far as I know, there is not a way to do this. It's a limitation we've run into before as well, and it probably arises from the fact that the branch GUID generator isn't run until t_relay() is called.
Thanks for your reply.
How about the index of the next new via branch, i.e., the digit after the . at the end of branch value (1 in the example below):
SIP/2.0/TCP 192.98.102.10;branch=z9hG4bK27b9.597e97c43da7ddd6be8520b662d616b9.1;i=5
