It is not clear what the issue is based on the information provided.
Are you trying to say you have '10.30.0.0/24' located on each of your branches, and they overlap with other branches?
You want to allow your other branches to access '10.30.14.1' on one specific branch?
This should be possible if you use a VIP to map the '10.30.14.1' to a different IP, then use that as the IP to contact the server.

Or, just want to know how to route a branch to another branch in hub-and-spoke topology?
If so you need to solve:
1. routing
2. phase2 network selectors
3. policies
at all FGTs on the path.
