i've understood what you need.
You're requesting a higher grade of "customization", having user profiles and sub-profiles that can be switched on the fly.
Yes, this requirement can happen under some circumstances. I make a thought about that, but will be a somewhat "bigger" change to "split" an user profile between static and dynamic informations, mainly because the requirement you can have to be changed on the fly could not suit needs of another operator that often changes another parameter that we made "static" into the profile...
I think this could be something for V2 or later V1 versions
