Dpad vs Stick

[UDb23]

I'm using both a Xbox360 wired PC controller and a Logitech Rumblepad with Retropie 3.8.1 on my Pi3.
On the Rumblepad there's a mode button that switches control from the dpad to the left analog stick (and back). How can I do the same with the Xbox controller ?
I know I could config single roms to use either dpad or Stick but a "mode" button is much simpler. Is it possible to configure a gamepad button to act like the "mode" button on the rumbledpad?

@UDb23 in everything except systems that use seperate d-pad and analog funtions (ie: psx, psp, n64...) i add this to the seperate retroarch files. this makes both the d-pad and analog work at the same time. as long as you have it configured to use the d-pad, this makes the analog work as well:

input_player1_up_axis = "-1"
input_player1_down_axis = "+1"
input_player1_left_axis = "-0"
input_player1_right_axis = "+0"

input_player2_up_axis = "-1"
input_player2_down_axis = "+1"
input_player2_left_axis = "-0"
input_player2_right_axis = "+0"

@edmaul69 Thanks a lot. That's a really nice solution.
