Wiring scheme help

Ok, first of all I would like to say that I have almost no idea how electronics work in guitars. I know the basic idea neg/pos... but as far as designing circuts I'm mostly useless.

That being said, I play a lot of praise and worship at my church and my main guitar is a 2007 Mim fat strat. I mostly use the neck and the brigde pickup during worship but it can be difficult for me to switch between them fast during songs. Is there a way to add an on/off/on switch that goes between the bridge and the neck pup? Ideally it would work like neck/5 way/bridge. If this makes no sense or is completely ridiculous just let me know. I can deal with just the 5 way if need be.
Thanks! Trow

You could replace the 5-way switch with a 3-way, you could also add another toggle that goes between the pu's directly and the 5-way as you suggested. That would drive me crazy having that though!
