It would be awesome to be able to schedule a post for a certain day and time. I know there's a bit of a workaround to do it, but it would be nice to have a feature that allows you to do it all in one click. Not everything I post is evergreen or needs to be repeated.
Example: Memorial Day is coming up and I want a post to go out on May 18th about it. Right now I have to do the "Schedule and send" option and click the "Only Use Once" option. It's not terrible to do those extra steps, but it would be nice to be able to schedule a non-evergreen post for a specific day and time.
