The most straightforward way is probably with a substitution function.
\version "2.22.2"
\layout {
\context {
\Staff
\consists #Measure_counter_engraver
}
}
repeatPercentWithCount =
#(define-music-function (count music) (index? ly:music?)
#{ \startMeasureCount \repeat percent #count { #music }
\stopMeasureCount #})
{
\repeatPercentWithCount 5 {
c4 c c c
}
}
