Nope. You are right on. Looking around myself. The closet anybody can come is binding the gamepad buttons to the keyboard. However this isn't quite working well. Example: binding r2 and square as 1 and 2 on keyboard activates function on the xhotbar but also opens map since that is the default action for square. Obviously this isn't ideal. Hoping they fix this. Apparently this worked in beta phase 3 by default (as the online user manual on loadstone implies) but somehow changed in phase 4 and onto release.
