If you play XBox or use a XBox controller on PC here is a tip that will give you more button mappings.
By default, clicking the left control stick puts you in "Alternate Control Mode" If you don't use it, change the setting from "Toggle" to "Hold" then you can assign buttons to "Left Stick + A", "Left Stick + B", etc...
You can't seem to unbind the left stick completely but changing it to Hold makes this usable.
The only time I ever used Alt Control Mode was landing, but there are "Landing Overrides" in the control scheme now that activate when you lower your gear that I found work better anyway.
