Hi Rick,

the code below doesn't create RehearsalMarks but it shows BarNumbers
as you want.
Store the Numbers to be shown in a list (-> my-shown-barnums)
Call `every-bar-number-of-list-visible´ as argument of barNumberVisibility.
Don't forget to add \override Score.BarNumber #'break-visibility = ##(#f #t #t)

\version "2.16.1"

#(define my-shown-barnums '(11 19 27 31 51 59 67))

#(define ((every-bar-number-of-list-visible ls) barnum mp)
  (if (member barnum ls) #t #f))

\relative c' {
  \override Score.BarNumber #'break-visibility = ##(#f #t #t)
  \set Score.barNumberVisibility = #(every-bar-number-of-list-visible
my-shown-barnums)
  \repeat unfold 70 { c1 }
}

HTH,
  Harm
