You could define your annotation (I assume by this you mean a single
measure with an example of the groupings) with variables that contain
their own \score of a single measure of the grouping you want. Then
use that variable as a markup for the bars you want to annotate.
This is a bit of a crude example - but might give you an idea.
\version "2.14.2"
\relative c' {
a b c d |
a b c d |
%The Tweak moves the markup left horizontally - this can be modified
as needed.
a-\tweak #'X-offset #-3 ^\markup {
\score {
\new Staff \relative c' {
%depending on what you want to remove you may also need to
remove the time sig stencil
\override Staff.TimeSignature #'stencil = ##f \clef "treble"
a'8 a a a a a a a
}
% The \layout { } is required. Do not remove it.
\layout { }
}
}
b4 c d |
a b c d |
}

I don't know this.
