Schedule Post (And expiry) in Channels for bulletins

With the delayed send option in peer to peer chat, i was really hoping that now that Channels have implemented by default Post/announcement tools and multiple channel chooser that a "Delay Send" tool would be coming as well

I would love to be able to set up a post for a channel(s) in a team, and then have it add to the channel the next day for example rather than right away without having to create a automation and form for it... (And expire or hide after X days option would be also an amazing add)

Then i could really start using it as a bulletin board tool in our school rather than external tools
