Use conversation templates in marketing emails

It seems too arbitrary that the content of a Marketing Email is kept distinct and separate from a Conversation Template. It is as if we are applying separate Marketing and Sales department mentalities to the tool system and unnecessarily creating divisions between departments.

We should be able to create content and based on user authorization be able to access snippets, documents, images, and other saved content. Authorization to view, edit, and/or use content should then follow rules based user authorizations, Communication Subscriptions, Workflows, Sequences, and 1 of the 3 unique types of email: 1) Marketing, 2) Sales, 3) Customer. Today, we have a Communication Subscription type for Customer Service/Care but we only have email content for Marketing and Sales.
