A quick tut while I think of it. I'm using Horizon: Zero Dawn as the example but the same technique applies to other games with weapon wheels.
1. Open XIM APEX Manager on iOS, Android (via Bluetooth) or PC (USB only).
2. In HIP, setup the binding for Inventory to an easy accessible button or key. In my case, it's the button behind the scrollwheel on my mouse. Don't bind Inventory to a thumb button for reasons that will become obvious below.
3. Swipe twice from right-to-left to display the Auxilliary 1 page.
4. Deselect Inherit on the Auxilliary 1 page.
5. Set Activation Key on Auxilliary 1 to the same binding as the Inventory binding.
6. Swipe all the way down the bottom of the Auxilliary 1 page to the Analog section.
7. In Left X, tap the left arrow to select None. For Left Y, do the same.
8. In Right X, tap left a few times and select Joystick Left X.
9. In Right Y, tap left a few times and select Joystick Left Y.
When Inventory is held, the thumbstick on the Azeron or Nav controller is now the weapon wheel selection stick, which is significantly easier than attempting to navigate the menu with a mouse using high sensitivity or Turn Assist. Movement is unbound on the Auxiliary page to prevent your character from moving, but is optional.
Note: this won't work on a keyboard, it's for analog input devices only.
