below you'll find an improved version.
Instead of defining a context-property, I use 'print-range as
subproperty of 'details of MultiMeasureRestNumber
You can now switch on/off by setting
\override MultiMeasureRestNumber.details.print-range = ##t or ##f
Of course you could define some shortcuts for them.
HTH,
