To Set Up a Pre-Tiled Source
The substitution table is a single table that allows you to specify a different source that should be taken when a specific source is selected on a bus. The substitution table requires either a Canvas or ME follow to be set up between the buses to trigger the substitution.
Tip: When you select the Source on the ME/Bus, the Substitution source is taken instead.
