Challenges adding large numbers of assets to a Data Product in Unified Catalog

The client's needs oblige us to add the tables from a SQL database into the data product; they've also got a use case for a massive file share.

We are hitting a wall in finding a programmatic solution to bring these data map assets into the Product, and the portal fails when trying to add more than 100 objects at a time.

Looking for a timeline for the release of APIs and tools to address this?
