ANY CHANCE TO ADD R3 SUPPORT FOR PS4?

I use a fightstick and in the Multiverse Events you can sometimes use an assist by moving the right stick in any direction. Any chance you guys could add R3 as an option in direction? I am unable to use the assist in Multiverse Events with my fightstick as it only has a button for R3 and no Right Stick directionals. Thanks! Love the game!
