Apex Legend PS4 controller custom settings [ Edited ]

[DANNYDARKO13]

Is there going to be a better Apex controller customisation option like the one you have for battle field one? I would like the option to take off melee or prone off R3 ( right analogue stick) I would only like to use R3 for looking around when moving and shooting etc. 

The present customisation only allows you to swop things around and at the moment when shooting I either go prone or melee or whatever I decide to swop on to R3.. really puts downer on my game play.. please help...
