More granular rotation values for projection parameters

There are probably methods around this problem, but I would love it if substance painter is able to have more granularity for rotation values when projecting masks. 

Meaning. instead of 90 degree intervals, create a slider which the user can specify exactly the rotation degree they want.  I do like the pullout menu for convenience though, so I would not remove that.  I would even add 45 degree intervals which would help with the above issues.  The tiling and other parameters of course would have to work with these non-aligned to axis rotations.

Thank you and keep up the good work,
