You can edit corridor region targets using the Edit Targets command in the Corridor ribbon tab.
BestPractice: Set region targets after creating the regions. For example, when creating regions, leave the targets set to “None” and proceed with creating the regions. After the regions are created, set the targets on the regions. This reduces the processing load because processing the assembly insertion points (during region creation), and processing the setting of the assembly targets, are two separate operations instead of one.
