Topic: let angles measurments disapear at special time

Maybe i just misread or could not find it.

I want an angle measurment en some tracking but i want it a long time in the video but not in the whole video.
Can you make measurement tracking appear and disappear at special keyframes?

So lets sayu the video is 3 minutes and i want measurment from 1:10 till 2:00 minutes for that angle. But in the rest of the video i don't want to see it.
