Is it perhaps as simple as:
%%%%%%%%%%%%%%%%%%%%%%%
\version "2.25.28"
pa = \fixed c' {
r2 g2*4/5 \glissando \hideNotes c'8*4/5 \unHideNotes
% or other note values and fractions to taste
a1
}
pb = \fixed c' { R1 R1 }
\score{
\new StaffGroup <<
\new Staff \pa
\new Staff \pb
>>
}
%%%%%%%%%%%%%%%%%%%%%%
