Is there an easier way to import input manager settings? (for Asset-store package.)

Hi, I'm working on an update to a couple packages I have on the asset store and I'd like to incorporate controller/gamepad support.

Thing is, I've seen the tips on copying the project settings while Unity is not running but is there an internal way of doing this? If so, it'd really make getting this set up far easier.

Reason is that I'd like to (if at all possible) make a unity-package asset in the folder that the user can click to install (like any unity package) that will set up the input manager's settings.

Is there a simpler way of doing this that could be applied to an Asset-store package or will the user have to do that drag-drop/overwrite thing each time (or worse, having to input them all in by hand?)

If there is, I'd really love to know how I can get this done. I'd love to be able to offer controller support that's as simple as I can manage it for my customers (and myself also.)
