Hey, guys.
Is there a mod that a competent tech could install that would allow me to get the 'outside pickups' Telecaster style setting on my 3-pickup PRS (Studio, in this case)?

I once had a Tom Anderson classic with three single coils, and the tone knob was a push-pull that would add the neck pickup, regardless of the setting on the 5-way switch. It worked well, but obviously on the PRS the tone knob push-pull is already being used to split the back humbucker. I am definitely not willing to part with that particular function. Ideally, I'd like to have this functionality whether the back pickup is split or not.

So, is there any way of getting that 'outside pickups' setting, without making any cosmetic modifications (extra mini-toggle, etc.)?
