Hi @chinmayis865517
1st part of your question makes sense where you want rollout sling:resourceType property from master to live copies which is general case. When you rollout from master copy, it's going to rollout components (along with its properties) to live copies.
What I'm unable to understand is 2nd part of question where you ask "master copy shouldn't inherit from its own blueprint" - does that mean you've either multiple master copies where one of the master copy is in live relationship with another master (let's call it parent master). Is that the case?
Also, if that is the case, then may I ask the reason for having multiple master copies?
Correct me if I've misunderstood.
Best regards,
