Not in the current version, but there is already feature request approved for a new kind of filter, ‘Note tags’ : FR: Tag filtering on PAGE tags for scanning tasks · Issue #122 · tu2-atmanand/Task-Board · GitHub
Your suggestion has given a nice idea for a improvement to this feature. Instead of keeping it specifically for ‘Note’s tag’, I think it will be better to make it more dynamic so user can specify the [property, value] pair. So, only notes which contains this YAML property and with the specific value will be only scanned for tasks, or will be ignored from scanning based on the option selected.
Thank you for this suggestion. Feel free to create a new FR on GitHub, explaining this in further details. Will help to discuss it better !
