GraphQL Mutation for Creating a blog | No author parameter

Hi all,

Unless I am going made, there is no option in graphQL to create a blog on behalf of another user is there?

i.e. in the input field something like "Author": { "user" : {"id": "user:1234"}}

This would be incredibly helpful as we use the APIv1 / v2 calls today to create a draft blog on behalf of a user so we can send those draft links to another user to enable Ghost writing.

Example:

A team needs to public a blog, however for consistency the team publishes all its public announcements from the director of engineering. The assistant (or another delegated user) needs to write a blog and make it appear as though it was from the directory himself.
