It'd be very helpful if more than one rep is looking at a ticket and RepB makes changes, RepA is not allowed to make any changes to the ticket until it is refreshed.
Example from today:
1. RepA opens ticket
2. RepB opens ticket, routes it to himself, and closes the ticket
3. RepA routes the ticket to RepB since the issue is something RepA needs to do
This results in the ticket being opened back up and the Audit History looking like something is missing.
