Not for bar numbers but for “anchors” that can be placed in a separate 
music expression, you could use the code below. You find the file 
alignTo.ily attached. This is a modified version of the file posted 
here: http://lists.gnu.org/archive/html/lilypond-user/2015-07/msg00235.html

The following commands are defined:
• \anchor, to be used as
        \anchor "anchorname"
• \until, to be used as
        s \until "anchorname"
or
        R \until "anchorname"
or even
        f \until "anchorname"
The latter for long notes is probably useful only if you use the 
Completion_heads_engraver.
• \quoteUntil, to be used as
        \quoteUntil "instrument" "anchorname"
Here you have to use \alignTo in the \addQuote command for correct results.
• \alignTo and \useAndAlignTo, to be used as
        \alignTo \anchormusic \music
The former only makes use of the anchors, the latter also uses the music 
of \anchormusic (f. e. key signature changes).

Thanks to the original authors!
