How to display tasks not included in any other query on canvas?

What I’m trying to do

I’m trying to display tasks not listed on any other card of the canvas. I separate my tasks along some folders, and query them on a canvas for better visualization. I have some other tasks who doesn’t fit on an any other exclusive card that i created.

I appreciate any help doing this, or even a tip about task organization itself.

Things I have tried

I tried using path does not include {{query.file.path}} . But it didn’t worked, maybe because tasks-plugin can’t read tasks on canvas.

I appreciate any thought, thanks in advance.

You can ‘Add note from vault’ on a canvas and as a second step, after right-clicking on the canvas card, ‘Narrow to headings or blocks’ to embed the part where you have your query.
