please make it possible for triggers to work on external con

[HeathCliff]

I play drastic on a nvidia shield portable which has a controller attached to it and drastic sees it as a external controller, anyways I would love to request the addition of triggers ( which are the buttons behind the shoulder buttons usually for those who didn't know ) because I would like them to be used as start and select since my device has the usual buttons ( dpad dual analog abxy and shoulder aka l and r ) in addition to a start button a volume button a back button and a home button and the start button I use as the menu button so please make triggers compatible thanks! Love drastic BTW its amazing
