Support custom tables in Aha! Develop

Our data model is such that every workspace in Aha! maps to a platform and we use a custom table to define the mapping. Since the field is mandatory for all objects in said workspace, we make the field mandatory when creating new features. We can't create features in an Aha! Develop parking lot since teams can't define custom tables.

We need to be able to define custom tables records for Aha! Develop teams to support our workflow.
