【Feature Request】Can we add numeric annotations?

With more marked locations, it's very difficult to find the location I want. I wonder if adding some identifiers could make this plugin more useful.

For example, label with actual names?
<img width="690" height="792" alt="Image" src="https://github.com/user-attachments/assets/cf091d0c-5703-4f67-90c0-c017fa2bc4e0" />
