I'm sure it's a lot more complicated than I think, but it would be great if callouts were scheduled by arrow point and not block locations. I have a design with work areas and lots of callouts but when I run a schedule for a specific area the schedule includes a lot of notes that don't actually belong to that area simply because a callout from a different area overlaps into it. Hopefully that makes sense.

At least this is what appears to be happening.
