I think this service would be more efficient if I could mock up my schedule on my calendar first, but adding posts where they need to go but not scheduling them yet. Then going through and adding the details and scheduling. It helps to be able to see what your feed will look like. Planoly is not nearly as good as Later but on that service you see what your feed will look like on the left side as you put content it. You can move posts around and if they're not schedule they just don't get posted.
