Requesting plugin for scheduling posts

Good day to all,

I have a habit to write posts in advance. Sometime dozen of posts then I won’t write again for weeks.

I am looking for a plugin that warns me if I schedule a post for a a day which already has a scheduled.

Even better, this plugin would automatically increment the date by one according to the date of last post. This should be decoupled or “reset”, since I may decide to write a post for a given date (like an anniversary) then continue on my daily writing as usual.

Does it make sense? Do you know a plugin for that? I did not find any on the official repository.

Bump the schedule and PostDate (especially the former) are close to it but not exactly what I am looking for.

Thanks !
