Marked leveling screws/wingnuts?

Just got the V4 extruder and my printer prints my highly detailed models superbly! Its print quality is even better than my other printers.

But, there's one more thing I'd like to figure out. On my other printers, they use wingnuts for leveling the bed. I've devised a system where I've marked one end of the wingnuts with a white grease marker so that I can easily read the wingnut's position on the fly and easily and quickly fix the bed level when I need to (Maintains a constant leveled bed that never changes, it's been working for weeks now.). I record the wingnut positions in a notebook for quick reference. Is there a way I could implement a similar system on the Makergear M2 so that I could easily/quickly read the screw's position so that I can easily/quickly fix it between prints without pulling out the feeler gauge and doing a full 10+minute calibration (Including cool-down and heat up times)? The screws are kind of tiny, so I'm not sure the best way to effectively/accurately mark them (At least with the grease marker.).

Sharpie. Simple as that. I did that on the bed leveling screws and on the Z Axis Stop Bolt, it helps to me, to visually see exactly how far I'm turning it.
