Add ability to schedule a message to the message composer
Let a team member compose a message and schedule it to send at a specific future time rather than right now. The scheduled message shows up in the conversation thread with a "scheduled for [time]" badge and can be edited or canceled before it sends. This is the lightweight, one-off complement to full automations: perfect for "send this note tomorrow morning" or "remind this guest about their checkout time in two hours" without building a whole automation flow.
