Quick creation of block links and block link synchronization

Use case or problem

Without changing the interface of document A, enter content in document B and link it to document A via a block link.
When the content of a block link moves from document B to document c, the block link in document A is synchronized rather than disabled

Proposed solution

Link creation:
Use the same method as for creating file links: write the link content and the block link identifier, and automatically create the block link with a keystroke or click.

File Designation:
This is accomplished by setting or entering a file identifier.

Automatic synchronization:
Synchronized in the same way as file links

Current workaround (optional)

Now I need to open document B, enter the content, and then go back to document A to create the link(too troublesome)

Block link failure problem cannot be solved
