Custom Ruler thats just Frames?

Just wondering, would it be possible to create a ruler that exclusively shows frame numbers, even when it exceeds a second? Just I’m sometimes dealing with work where I’m told the audio needs to last, say, 227 frames and it would be good to not have to mentally calculate that into seconds every time.

‘Timecode’ and custom '30fps (user) rulers only show frame count when zoomed in VERY close (about 1 frame per inch as my display shows it!).

No?

Anyone at Steinberg?
