Text above lines aligned with no notehead

[Matthias Bry]

The following:

%%

A([alt:test]) 

Does not print "test" above the staff, nor does

%%

A([alt:test] ) 

Is there any way to print text above an intentionally blank section of the score?

The goal here, in particular, is to use [alt] along with NABC, given that all GABC snippets that actually have notes, also have NABC, and therefore cannot have [alt].

Thank you,

In Christo,

Matthias
