Change rotation to 1° with Gumball's arc and Shift key held

Rhino Rhino for Mac

Hi everybody, this is my question: When I rotate an object with the blue Gumball’s arc while holding shift, it rotates my object in 5° increments. Is there a way to set this value to 1° or even smaller? Under Modeling Aids (see screenshot) I found no option for a setting with the Shift key held, only Ortho Snap, but that can’t be changed to a setting as low as 1°.

If you do a gumball rotate without Shift and type 1 Enter while holding the grip, it will start rotating in 1° increments (for that rotation only).

Edit: This only works if Grid Snap is turned off (in which case, normal Shift dragging is fully smooth anyway).

Is this a bug? I would expect setting an explicit rotation increment like this should override grid snap.
