Wholesale accounts using member areas

Hi All, 

Ive noticed there are a few posts regarding the member areas and setting up a restricted but free member area that offers wholesale pricing to trade customers. I believe there was no option for the members to be approved and they were granted immediate access upon signup. Does anyone know if Squarespace has changed this yet? 

Im hoping to use the same inventory list but offer wholesale pricing. However I would like to be able to approve the membership signups by ensuring they add in an abn & business details and I can check they are legitimate before granting them access. 

Thanks
