Can I Reference Parameters in the Parameter Center and Target Instances Across Regions?

Based on safety production requirements, users are not allowed to reference parameters in the Parameter Center and target instances across regions.

For example, on the Execute Script page, you click Parameter Center in the Script Input Parameters area. On the Parameter Center page, if you set Region to CN North-Beijing4, set the same region when adding the target instance. Otherwise, an error will be reported and the script cannot be executed.
