No, I don't know how/if that is possible.
But if that could be made possible by adding a feature to LilyPond I 
would be extremely interested to investigate how to do that for PDF too, 
that is to create "Optional Content Groups" and place grobs on them.
That would for example make it possible to add annotations or to add 
solutions to exam sheets that can be simply switched on and off in the 
PDF viewer.
