Shopify B2B - Prevent new products from being added automatically to a catalog

[epetroel]

When creating a new Catalog in the admin, I see there is a checkbox that says "Automatically include new products in this catalog."  However, when creating a new catalog via the GraphQL API (catalogCreate), there does not appear to be any way to specify that behavior. 

From what I've seen, it looks like when you create a new catalog via the API, Shopify assumes that you want all new products to be added to the catalog.  For my particular use case, I don't want that - I just want the catalog to contain the items that I add to it (to limit the products a specific B2B customer can purchase).

Am I missing something, or Is there any way to accomplish that via the API?
