Combined mappings + option to rebind LT and RT request

Is your feature request related to a problem? Please describe.
partially, described below

Describe the solution you'd like
Please add option to bind things to more buttons than one (for example: left thumbstick + A). I've recently bought a controller because some games are better played with it, and I tried to play minecraft (both java and bedrock) but since bedrock has defaultly controller support its without problems. On java, i tried two mods. This one and MidnightControls which is in my opinion worse, except option to make combined bindings. I liked this one more but I will not play java with controller until this feature is added. I personally use many client side mods that enchance the game, but since controller does not have many buttons, It will be nice to have option to make combined mappings.

Second thing is that I tried to switch bindings for LT and RT and it didn't register it. Idk if it is bug or needs to be added but Im letting you know here

Describe alternatives you've considered
none

Additional context
i dont have anything

The issue does not name files, tests, or entry points. Start by locating the controller binding configuration and the handling for LT and RT, then determine how multiple inputs could be represented. Done means combined bindings can be configured and LT/RT rebinding works, with coverage for both behaviors.
