Acoustic API for Creating Content at a Given ID

I was investigating how to move contents from one subscription to another by taking only updated item during a specific time interval. There is an endpoint that enables us to retrieve the contents. 
https://developer.goacoustic.com/acoustic-content/reference#get_authoring-v1-content-views-by-modified

Our contents have references to other contents, and this is where the problem lies. 
When creating contents with the API (https://developer.goacoustic.com/acoustic-content/reference#post_authoring-v1-content), this content will have a new item Id.
All the references would break. :( 

Similar to the API for creating a resource at a given Id (https://developer.goacoustic.com/acoustic-content/reference#put_authoring-v1-resources-id), I wanted to know if there is something similar for creating contents.
