Yes, the simplest would be to put the override syntax in a separate
Denemo Directive (you can use the command

Command: Insert Lilypond
Insert or edit a directive in the LilyPond music typesetting language.
This can be used for extra spacing, transposing or almost anything. See
LilyPond documentation for ideas.
Location: Object Menu ▶ Directives
Internal Name: InsertStandaloneDirective


 to do this, but you will want to improve the display by editing it
after creation, and then perhaps making a palette button to insert it).

You would miss out the \once bit of the syntax in this case so it
applies to all the brackets following.

Sorry, yes I should have put (d-MoveCursorLeft) after the first command
as it creates the Denemo Directive and moves to the right straight
away, so that the subsequent commands create new directives instead of
editing the old one. There is a wrapper function that does a whole
bunch of this for you called (StandAloneDirectiveProto ...) which is
used in the script for that InsertStandaloneDirective command I
referenced above. But to keep things simple:

 (d-DirectivePut-standalone-display tag "This will label the Denemo Directive")
 (d-MoveCursorLeft)
 (d-DirectivePut-standalone-tx tag 20)
 (d-DirectivePut-standalone-ty tag -20)

would do the trick (the subsequent d-DirectivePut-... are editing so
they don't move the cursor right, the cursor always moves right after
inserting an object).
