Default On the fly map switching with a switch? 15 wrx

Okay so kind of an odd question, but I can't seem to find anything. I have a 15 wrx, and currently running a phatbotti e tune, I have a nameless cat back (soon to add their single exit track axle-back instead of mufflers, then going to add a quite muffler and a cut out) an intake and a boomba. Now onto the question, I've seen a ton of videos of stis that can change their map/exhaust cut outs with their driving mode selector, and I hear it's possible to do it on the cvt wrx, but is there any way to do it with a switch on the 6spd wrx? I just want to get good gas mileage with a conservative tune, but then be able to go with the flick of a switch. I got gapped by a stock si with my eco tune on, and I can't do that again. Also, I should note that ever since I got my AP the ECU real-time option has been "disabled by map" , this has been for all my maps, ots, and both of my ron tunes I've had done, I'm trying to figure it out.

I seriously doubt it because the ECU would need to be pretty advanced to keep two tunes and be able to instantly switch them.

Plus, you know a more aggressive tune doesn't just "use" more gas, it's just capable of it so if you want good mileage just drive conservatively, that is how it's done.

I have a 650hp supercharged vehicle in addition to my STI and I can get 30 mpg in that thing if I just cruise casually and stay slow and don't pass or have any fun.
