New Syncing or suggest a solution to the problem

[l-n0-0b]

Good day.

Description of the problem:

There are 2 places.
It is necessary to sort of mix files and subdirectories in them.
But there is a problem, they cannot be synchronized by date, as this is unreliable.

In either of the two places, there may be broken or incomplete files.
You can add the command
rsync -avz --checksum --detail-changes --update
But then the new files will be replaced with the old ones, even if they are bad.
And without --update

Suggestion:

When checking with the --checksum command
To make the program issue a request on different files and directories.

So that I, as a user, can decide for myself and Choose YES or NO for files that do not match in the checksum.

These files are very important, they need to be brought to a single value. But at the same time, do not replace good files with bad ones (for example, a copy error, incomplete files, etc.) even if they are new or with the same name or weigh more.
