Shorter/Simplified Wait Command?

I’m sure this question has a simple answer but I can’t seem to search my way to it.

Is there a way to get Inform to recognize “wait 8” or “z 8” as “wait for 8 minutes”, without having to totally re-write the wait command built into the system?

See the Recipe book §6.11. Waiting, Sleeping
Example: Nine AM Appointment
