Different EQ launchers?

I have a question, maybe it's simple and I'm just missing something obvious?

I have ISBoxer setup and running fine for my characters on Live servers.

I just tried to setup a character on the Test server (I have 3 separate EQ folders, Live, Test and Beta).

I selected EverTest as the game folder but when I tried to load that character it loaded on Live.

Is it possible to setup ISB to use the 3 different versions?

Attached exported config.
