Vendor Portal and AB5?

We've made a bunch of updated to the documentation that we require from vendors in light of AB5 in California. Of course, the vendor portal isn't set up to collect this type of data so essentially we put it in the independent contractor agreement. It works, but that means we still have lots of manual data review and entry as we onboard new vendors. So, question....

How to others handle the need for additional documentation from vendors in light of AB5? We require documents showing that vendors can 'prove' they are freelancers or incorporated.

And for @XTRF, is there any plan to add features to the vendor portal to support AB5 documentation?
