I re-read what I was asking. What I'm trying to do is, while I'm already in ADS looking at the target, if I need slower\finer movement I can press the Nav Bumper while still holding the ADS Trigger to activate the finer movement. Is it possible to activate a config with 2 buttons? I guess I can always create a profile and set a hotkey to switch between profiles.
Good question. In The Division, I hold left-click for the ADS translator for normal ADS sensitivity (left-hand), then hold a button bound to D-Pad Up with my pinky (right-hand) when I want Sniper mode. That's all done on the Xim and it definitely works.
Here's the Xim code so you can see how I set it up -

<<< XIM4 END PASTE <<<
For Destiny, I'm using a Titan One with a sensitivity adjustment for sniping mode, which is bound to Sprint. Sprint breaks ADS in Destiny, so I had to write some conditions to handle that while ADS. I could easily have done it by binding Snipe to R3 (Player Highlight) on the Xim, but I use R3 for something else in the Titan One script.
In your case, hold ADS, then the Snipe button (or Snipe could toggle, don't forget to set Deactivation keys), but you will need to tweak the bindings on Snipe and probably ADS to disable the Jump binding to prevent yourself from bunny-hopping while ADS.
The biggest issue is how Xim4 handles the Jump binding while ADS and Sniping. It can be disabled on the Snipe config by binding something else to trigger (don't Inherit Buttons from Primary), but I don't know how that flows through to HIP, which is why I suggest doing the same on the ADS page. That creates a problem where you can no longer Jump while ADS, but how often does that come into play? It's usually Jump, then ADS, which would be unaffected.
What game are we talking about? I can try it out and test for problems.
Have you got a Titan One? This sort of thing should be easy to do with a script if it doesn't work on Xim.
