Is that some kind of standard notation you use in your project ?
I have to admit there is an idea here.
If we transcribe that (inserting items width lenght) for creating empty midi items, it could be a killer way to write long and complex tempo map, using my
EEL : Insert Time Signature From Selected Items script after importation :P
Anyway, I don't plan to use that soon, it is just a pure theoretical concept.
