ME - legendary - buttons key mapping

Hi. 

Is there a chance to add free button remapping.

For example on playstation touchpad holster weapons but if you need to check map you need to press options and choose it from menu.

Also pressing L3 to crouch is exhausting. I don't really understand why allowing to rekey buttons isn't every game standard at this point especially that almost every developer now is trying to advertise their games as accessibility friendly.

Mako vehicle - we could use an option to drive one way but shooting in different. Vehicle is  automatically turning direction we are shooting in.

Thanks!
