Form Availability Controlled by Date/Time

I would like to be able to control when the form is available for submission by date/time.

For example, the form could be live starting on X start date/time. Until that time, a default message indicating when it will go live appears. After the initial date/time, the form appears per the Advance > Behavior > Behavior Type settings. Then, on Y end date/time, the form is no longer available. It would then show a default message that the form is closed/no longer available. If a registered user has a submission on file, it also continues to show that user’s submitted information (or last submission, depending on the Behavior Type).

Right now, After a deadline, I go in a manually take out the shortcode. I might be able to use some other plugins that control posts and display/include said post onto the page, but I think that it would be more streamlined to be controlled within Form Manager itself , especially for less experienced site admins I work with.

Maybe it is something that could be added to the Conditions.
