Azure nested templates

Let’s say I have one Azure template in ManageIQ(CloudForms actually) which is linked to another nested templates in Azure. Do I need to have those nested templates also in ManageIQ or is it enough to link the main one to Azure? If I need them stored in MIQ, how to link them from the main one?

A link in the main one is sufficient. You don’t need the nested ones in ManageIQ.
