OK, makes sense - I understand.
We can probably use the "/" character.
But this being the case, I think we have to modify the Help screen where it states: A period denotes upper and lowercase alphanumeric and ! - / (eg. 0 through 9, A through Z and a through z, along with exclamation, dash and forward slash).
Here is where I originally thought I could use the dash for Depts, based on the Help description.
