I doubt it.
Imagine the grief when you schedule the wrong package for a site and you are zuzzing away.

I watch all my uploads and test them right away.
As I FTP into Cloudflare-enabled sites, Clourdflare would then it have to recognise an upload and switch to Dev mode so I can purge server caching?

Your need is rather niche.

I would also be loathe to send out an email of any consequence on a timer.
I have been a recipient of such a communication that pinged back to the originator, who had also set up Out of Office, and the resulting ricochets effectively had the effect of a DDOS.
