Here's the scenario, I want to list all of a customer's appointments, ending with the "last" one, regardless of whether that was in the past or scheduled for the future. I have come up with a few words for that: last, final, latest. The trouble is the meanings of the ones I have come up with are ambiguous.
Last and final could imply that this is the customer's last appointment ever, and they won't be coming back in the future. Latest could mean the appointment that occurs latest in the day, or the one they showed up the latest for.
So is there a single word or short phrase (eg "most recent") that unambiguously carries the meaning of "last chronologically, for now."
Edit: Realised I was getting downvotes for not filling out all the single word request criteria so
Sample Sentence: "This fields represents the customer's last appointment.
MW had "bottommost, closing, concluding, final, hindmost, lag, latest, latter, rearmost, terminal, terminating, ultimate" for synomyms of last.
