Jog 1 frame at a time with AI knob?

Is there any way I can move the cursor exactly one frame with the AI knob no matter how close or far I’m zoomed? I set my grid type to 1 frame, but I have to be zoomed in a certain amount for it to move one frame. Any more and it’s less than one frame; any less and it’s more than one frame.

I’m happy to report that this is now working since I’ve updated to Nuendo 6.5.4. Pretty awesome. Thanks Steiny.
