Change the increments for moving an object+1 finger modifier

[MoonaticDestiny]

So if you rotate an object while holding down a 1 finger modifier you can rotate that object in increments of 15*. So rotate 15, 30, 45 and so on and so on.

However, if you move an object while holding down a 1 finger modifier you can move your object in increments of 45*. I dont like that. I want to change this. I want to move my object in increments of 15*. 15 degrees because I want my rotation and move increments to be the same and I want my brain to register and learn them as increments of 15 degrees. Not 15 and 45. I want to keep things the same. 

In another post I had requested a gestures category in the preferences to change my resize gestures so now I need the ability to change these increments for my rotate and move to be located in this gesture category in the preferences.
