Thanks for those replies - very helpful.
Oddly enough I’d not really thought about that workaround.
I can see some fun and games with time signature changes during a cue but using track versions might help there.
It reminds me of a midi track I set up on one of my templates to control midi gates [cubase midi gate plugin and Cytomic Drop midi input] - where I created track versions for different rhythms and quantized lengths etc.
At some point I’ll build that idea into a template - but it’ still seems curious that this pretty basic function isn’t part of the standard DAW!
