change angle resolution of "target position"

[Lookerksy]

In InfernalRobotics_v3.0.2 + KSP 1.9.1, I find the Robotic Part has angle resolution ( 1 degree ) in KSP Field "target position".
I will get 77 degree if I set 76.54321 degree. It's a rounding value.
I don't like this feature. I want precise input. like 0.0001 degree.
Is there any way to angle change the resolution to a smaller value?
Thanks.
