Yes, in fact you're already doing this, explained below...

The short answer is no.  Whether (for example) a PianoStaff context can
contain ("accepts") a ChordNames context or not is not a property of
ChordNames but a property of PianoStaff.  So you have to tell PianoStaff
(and friends) to accept your new and unknown context.

You can just do it once and put it in an include file so you don't have to
do it again.  That's what I do.

(I suppose it would be possible to change how LilyPond handles this so that
unknown/custom contexts were accepted by default by other contexts (rather
than rejected by default).  Or, probably better, introduce some kind of
"passes as" property where you could tell other contexts to "treat this
context like X context for purposes of accepting/rejecting it".)

Hope that helps,
-Paul
