In the CRITERIA section of the Settings.... you can limit (filter) the objects by LAYER or NAME or PEN COLOR, etc. It will be your job to make sure all the stuff you want in the schedule has that unique identity (all on the same layer, for example) so that your schedule will look right.
iv been doing it by using the lable tool.. lable all of one grupe of itmes i want listed with for example "S1" (for schedule 1 obviously) then if i want another groupe lable them as S2 and so on.. then filter them by there lables..
thho if u need to actually use the lable tool for these items then u will need to work out another way
