So here’s the idea: For the public we might have a category that uses simple English to describe, such as “I need somebody to fix my computer.” However, on the inside, we’d like to see this selection as “Trouble Ticket” or something similar. They’d be the same "category, but the verbiage would be different between insides and outside.
This would have to be customized in the portal template, there’s not a way currently to do that.
Once concern I would have is you then end up with customers and staff using different verbiage for the same thing. In some cases this may be confusing, though it of course depends on your particular scenario.
