There is currently no way to change an owner of a ticket. We'd like that a lot, and have following use cases:
1) Ticket submitted/forwarded by 3th party or by automated system that doesn't set the correct From or Reply-To header.
2) Ticket with lots of parties involved: common practice is to split those tickets, but it would then be nice to specify a different ticket owner/submitter
3) Tickets generated by staff, based on eg a phonecall. If there is spelling error in the ticket owner address, we keep carrying the bad emailaddress, unless we close the ticket and manually copy it over to a new ticket...
Complete We've implemented this suggestion!
