Thanks, Mike! I appreciate the explanation.
I tried the "Embed Annotations" option, and it does work, but I noticed two drawbacks that limit the advantages of using snippets (considering that my workflow mainly consists of applying fingering to organ music scores):

1. The editability of annotations—especially deletion—seems to be only partial. Deleting annotations appears to happen in "blocks" rather than allowing precise removal.
   
2. Since the PDF seems to be rewritten each time the annotation editor is closed, this process can take a long time for large files. In my case, a ~100MB file takes 40 seconds to process on an Windows 11 PC (i7-4770/32GB/3.40GHz)).
   

Granted, in my case, an alternative could be to embed the annotations only once they are finalized.
I assume this behavior is due to the inherent limitations of embedding annotations directly into the PDF. Are there any alternative solutions in development or under consideration, similar to how ForScore handles this without the same performance issues?
Thanks again for your help!
