Enhanced Sandbox Test Data Generator fields

It appears that when creating a test sandbox company using the data generator, the only field one can add is the company ‘jurisdiction’: Sandbox Test Data Generator API: Create a test company

We would like to create a detailed sample company in sandbox with officers, charges, filing history etc and subsequently use the Public Data API to get request and retrieve this information in the sandbox environment for testing purposes. Will it be possible to do this at some point? Thanks
