Once the Digital Twin is started, the following is visible on an entity:

A blueprint ID is automatically assigned. It is a randomly generated code/id of which the user can change to a specific name. The user needs to ensure the name they choose for the blueprint isn't the name of an existing blueprint,as the DT Template takes preference and the existing blueprint will be overridden, unlinking from any entity already linked to that blueprint. Alternatively, the user must ensure that the blueprint being created with the DT's properties match the existing blueprint's properties, this way current blueprint links will not break.
