Consolidate controller inputs POE1 - POE2

I have wrist problems and play both POE1 and POE2 with a controller. Can you please consolidate the inputs for the games or at least make them configurable in POE1? Low priority I'm sure but for example:

- L1/R1 switches tabs in POE2 but moves tabs in POE1 (L2/R2 to switch). Very annoying when playing all leagues of both games.
- R1/L1 uses life/mana flasks in POE1 (not configurable) but is configurable in POE2. I like my primary "map clear" atttack on R1.
