correct in AutoTrack professional there is a rule that needs to be added to each category that you want it applied to:
Hour/Date Restrictions (Song/Link Card)
Add the rule to one of your categories, then there is a button that allows you to copy it to all of the categories.
This can be treated as either a Rule (enforced) or Guide, to change how it is applied just double click on the rule in the list.
Hope this helps.
