Right now, we have one brand in our Zendesk instance - A. The ticket numbering is fairly normal, e.g. #76867, #76868, #76869, etc.
We are about to set up a new additional brand - B, and we will be migrating tickets from a different ticketing system.
I carried out a demo migration of roughly 20 tickets and I noticed that the ticket numbering continues for those migrated tickets - #76870, #76871, etc.
A new feature, that would be useful, would be to make it possible to somehow distinguish those migrated tickets for the new brand and also newly created tickets for the new brand by adding some kind of prefix/suffix to the ticket number.
E.g. brand A would have regular numbering, and brand be would have the prefix B- so the ticket id would look like #B76870, #B76871.
