Input customization

Hello. I was wondering if battlenet could implement an input customization feature. Steam has a feature where you can edit controller inputs for whichever game you want. This feature allows me to change/unbind my inputs. This is not within the game itself, but the changed inputs will still apply in the game. This feature is really helpful for lots of people. Also, they’re are plenty of older games that dont give you the option to change button layouts or unbind certain inputs. This feature would really help with this. I was hoping you guys could implement this feature.
