How to assign channel 5 to the gear switch?

I was wondering what's the easiest way to assign channel 5 to the gear switch on the devo 10?
I am using the Naze32 for my quad and I want to flip between arco and auto level...
I just used one of the existing models files and I just want to alter that.

I'm a newbie with both the naze32 and tx so I'm not 100% sure.
Thanks for any help

Do I have to be in advanced GUI to access that?
I'm just not exactly sure where to access that.
When I said newbie I really meant newbie.... Sorry

I just checked in the deviation manual and answered my own question
Thank u!

I just went and changed to advanced GUI, went back to the model menu, went to mixers and scroll down to channel 5. I wasn't given the option based on what you said....
This was my view

That did the trick!!
Thank you so much for this advice!!

I find that the deviation manual is very tricky, especially to somebody new like me who doesn't have a lot of technical knowledge on programming .

Is there a manual out there that is written in more plain speech? I tried to search for this answer online before I came here and asked anyone. There could very well be such a manual or a place where everything is centrally located but I couldn't find it.
Your explanation on how to do what I did was very easy to understand Haha.
Thanks again for briefly holding my hand through this step.

I wrote a tutorial on writing a model config . It would have covered this issue. Walks you through configuring a model from scratch, in great detail. Might be what you're looking for..

Sweet! Thanks!
I would be very interested. I hate not being able to use the things I own properly.
