Looks like somebody had already suggested such a feature.
The only difference I can see is that they’re considering alternative ways to set those timestamps, while yours adds the option to edit this via the user interface.
Please search before posting duplicate posts to avoid distracting votes from each other.
If you want we can move your post into that other suggestion to add the angle of doing this through the UI. Otherwise I’ll close the post so you and others can vote in the existing suggestion.
