different ui per toon

[Solitas]

I apologise if this has been addressed before, but I can't find it with a search
Is it possible to have a completely different ui per toon, for example, I want thorui for my necro, and fetish for my assassin, not necessarily those for that but I do have certain individual custom uis that I would like for my different characters.

I don't know if it would be a simple change to the eq2.ini, or if I have to mod the server_toon.ini

Thanks for reading
