It depends on how you want to include the symbols in existing music;
for example, if you define them as TextScriptEvents, then you could
simply call them as \push and \pull following notes, or create a
context (like Dynamics) to contain a line of symbols attached to
skips.

If you wanted to use an engraver, you'd probably need to think about
sending an event to represent the push/pull, but it ultimately would
end up generating a TextScript.
