[atlas] [UDM] What value to give to 'requested' when 'type' = 'msm'?

The documentation <https://atlas.ripe.net/doc/measurement-creation-api/> says: "probes": [ { "requested": 1, "type": "msm", "value": 1000002 } ] but, from my tests, if you do so, you get only one probe, whatever measurement #1000002 actually used. To get all the probes, I had to indicate a very large number in 'requested' (unless you remember or count the actual number).
