Retropad Keyboard Mapping defaults

Are there any plans to set defaults retropad keyboard mappings for player 2 inputs? I use an iPAC ultimate in my arcade cabinet, and i’ve seen quite a few posts regarding confusion around mapping their controls. The iPAC defaults to a MAME control scheme, which I know has some conflicts with RetroArch’s and i don’t care to reconfigure the iPAC to the settings for RetroArch, I know i can map them myself, I was just thinking if there were defaults already defined for all the buttons on player 1 and player 2 (L2 and R2 don’t have defaults for player 1) this might help a lot of user out, since they would just need to load the correct configuration onto the board.
