It would be great to be able to set a schedule so that when placed on a sheet it was filtered to only show elements visible on the sheet, similar to the way a color fill legend can automatically filter itself to the view it's placed on.
This would be of great use for schedules of room/space data, equipment data etc. etc.
It would need to be a dynamic filter so that the same schedule could be placed onto multiple sheets, with each showing different elements.
