feature request : percent repeat counter

[Ishizaki]

Hi, 
I would like to show repeated number onto the percent sign, but even most
recent lilypond seems not have this feature.


          2   3   4   5                     <---- I need these
[music] | % | % | % | % | [another music] |...


I hope this would be available someday.

Cheers,
