Camera variable for custom view?

Using Touch Portal to set views in Fenix A320.

To switch to the pedestal, I use:

2 (>A:CAMERA STATE, Enum) 2 (>A:CAMERA VIEW TYPE AND INDEX:0, Enum) 5 (>A:CAMERA VIEW TYPE AND INDEX:1, Enum)

This uses an instrument view as described by:

https://docs.flightsimulator.com/html/Programming_Tools/SimVars/Camera_Variables.htm

I have not been able to find the variable to switch to a “Custom View”, there is only “Quickview”. As a workaround, I assign a key on the keyboard to the view, and send this key via Touch Portal. This is kind of ugly and depends on the simulator having the focus.

Any ideas?
