[atlas] What is the trick with "+Reuse a set from a measurement" ?????

Hi Team, I’m trying to use “+Reuse a set from a measurement.” (See https://atlas.ripe.net/docs/getting-started/user-defined-measurements.html <https://atlas.ripe.net/docs/getting-started/user-defined-measurements.html>) I’m going back to my own measurements and trying different Measurement IDs. None of them work. I try from someone else’s test. None of them work. Q. Does this function work anymore? Barry
