Removing a time signature only once

[Christopher R. Maden]

tl;dr: How does one remove a time signature completely (not just
transparent) without removing the time signature engraver?

I have a song that changes time signature for the chorus (and then back,
obviously, for the next verse).

In the printed version, I do not want to re-assert the time signature
for the verse; it is the same as the introduction.  However, in the MIDI
unfolded version, I need to (to avoid bar check warnings, at least).

Making the time signature transparent works, but it leaves horizontal
space for the time signature, which is awkward.  Every reference I’ve
found while searching says that the way around that is to \remove
"Time_signature_engraver" from the Staff, but that will wipe out *all*
the time signatures, not just the one I want to avoid.

Any suggestions?
