Expose the hardcoded Precision Key

Hello @mano-wii
Saw this new feature in Blender.Today LIVE #139
https://developer.blender.org/rBb926c9f34587651b6c39dc43608a79dd6367e9a8

Is there an improvement planned for how exactly I want to be precisely when pressing Shift?
For example,
I want with Shift holding move by 1/10 of my current specified Scene Units.
Is it possible to implement?
