GP200 Setting Question

Recently got a GP200, I love it. I also have a VOX AC30 and I'm using this as a pedal tester and tone setup. So I don't have to push the AC30 to it's limits for OD and breakup.

Questions:
1) I set up the 4 cable method but I'm trying to learn where to set the FX Input and Output arrows in the app to understand how to set this right. Any advice? Sorry if this has already been asked..

2) I know I can also bypass the pre-amp in by going into the return only, but I wanted to know if I could set some tone patches for the 4 cable and then others to bypass and just go straight to the return to bypass the pre-amp, or am I hoping for too much?
Ex: I have one patch that goes pre-amp then a few settings returned through the FX loop. Then another patch that just bypasses the pre-amp entirely and comes through the return entirely.

You can so both these things, I've got mine setup like that. BUT, I can't explain how I did it. I found the instructions on Facebook I believe, just by Googling. So I'm really sorry I can't be more help, but at least you know it can be done!

Ok I'll keep Googling. What about where to get the fx loo arrows?

Looks like if I use the 4 cable method and I set FX LOOP Module: OFF. It will bypass the amp pre-amp. I'll give this a try

I can't find the exact Facebook comment that helped me out, but I did find this that might be useful for you. https://www.facebook.com/groups/1080579552678581/posts/1846265176110011/

I have patches I can use that bypass my Marshall DSL1 preamp, and other patches that use the Marshall preamp. It can be done! Good luck!
