Yes, I’d suggest this becomes another drop down option in the “Default location for new attachments” as you mentioned.
The use case can be as below:
- Note can be started quickly at one place but later on be moved to some other places during its life span
- A lot of screenshot and file attachments can be added to note during updates of the note in its life span
- If attachments go with note, these attachments are always “attached” to the note no matter how I move them and I can easily locate all of them in the Finder / File Explorer then zipped to share with others who don’t have Obsidian or for other purpose like backup
- It will also be easier to remove some notes along with attachments quickly in the Finder / File Explorer without checking reference relationships in the Obsidian tool
- Also it naturally avoids large amount of orphan attachments (i.e. quick screenshots, PDFs or other files) when notes are deleted
