single line staff for measure numbers

Is there a way to do measure numbers as per the attached image? The numbers are on an instrument-less single line staff with no rests. I’ve tried to fake it using a single line percussion instrument but I can’t get rid of the default rests without removing them for the entire score. (Screen grab is from Sibelius)

There’s no way to do this yet, but the new timecode staff added in Dorico 2 for displaying timecode and markers will allow us to add this in the hopefully not-too-distant future.
