JR XP7202/DX7 (Aux) 2 position switch convert to 3 position?

[Autotechnica]

Hey guys,

I have a JR XP7202-H which I've converted to 2.4GHz using a DIY FrySky module. The transmitter is essentially a Spektrum DX7 in almost every way. Anyways, that part isn't important. I'm a bit of a noob when it comes to electronics. I have a very basic understanding. I have a DJI Naza mounted to a T-rex500 Cobra AH-1 scale body that requires a 3 position switch for the 3 modes (attit/GPS/Normal). I do not wish to use the 3 position switch from the flight modes as I want my idle ups. My question is that I want to convert my 2 position "AUX2" switch to 3 position. Is this possible? It's just an analog signal and it looks like a 2 position switch just produces a value from 0-100. Can I get a 3 position switch and have it produce say 0-50-100? The exact numbers aren't important and I can fine tune which portion of the signal activates what in the DJI software. I'm assuming some sort of resistors or transistors will be required to do this? Any help would be much appreciated. I'm also terrible at program mixing. If there's any other way you guys know to achieve this even using the current switches available, please let me know.

thanks!

Thats going to be a No.
The logic in the programming for that path is to see an open close option.Its not going to process a proportional value.
