Description

When a template is instantiated, any Controller Services within the template are created. If the template is being used as a repeatable building block, each instantiation will create yet another instance of the Controller Service(s).
First level approach: Suggest there is an option when instantiating a template to not import/create corresponding Controller Services.
Second level approach: Allow selection of which Controller Services should be imported/created
Third level approach: Allow a mapping of Controller Service to existing Controller Service
