Access to multiple test companies in sandbox

We were wondering if its possible to get access to multiple sandbox companies for our account for testing purposes? Right now it looks like we can only create one when I’m on this page

Hi @g.friedman,

Our apologies for the delay on getting you an answer on this question! Unfortunately, at this time, you can only get access to the sandbox you created. However, you can use that environment and create an account there if needed.
Please let us know if you have any further questions on this!
