controller mapping (like Steam's action sets)

Hi, wondering if its possible to map Legion GO controllers with action sets similar to Steam, where pressing left trigger allows me to map all my buttons to a new sets of inputs.

In my Steam setup, as an example:

Normal: ABXY buttons map to 1-4, left directional pads map to alt-1 to alt-4
Pressing LT enables "Action Set 2": allowing me to map ABXY to V,G,R,T and left dir-pads to F1 to F4.

Is this a way to achieve this somehow?
