This would be nice, but you could also just run through the autoposter twice, right? You could run through once using the morning window, approve the posts, then you could run through a second time in the second time window and approve the posts. Alternately, you could go into the queue setting for each social account, establish that you should only post in select windows, and then select "queue settings" when you go through the autoposter instead of "time range." Essentially, I think what you're requesting is already a feature of the platform? Feel free to send me a message if I've been unclear on these points or I'm misunderstanding...
