change angle snap for gizmo 3d zbrush 4r8

so when i rotate a polycylinder so that the flat area is on top, i always use deformation, type in 22.5, and its becoming really tedious as of late. Is there a way to change gizmo 3d 5 degeree angle snap to a custom value? so that i can snap 22.5 degree at will, anywhere without going abck to the center of the world or doin it on another tool first?
