My use case: I want to purchase T4 personally and experiment with the local Custom AI feature. Later, I would like to use Alice's T4 capabilities in a professional team setup, e.g., with side hustles, I start as a freelancer. My questions:
(1) Can I sign up to T4 with a personal email adress, without an immediate domain setup, and add domain information later (in the beginning, only I would need a login account to Alice)
(2) After adding the initial domain (abc.com) and over time, can I change the domain (e.g., to xyz.com) multiple times? I would only need to use one domain at any one concurrent time.
