Free Lincenses in Business Account

Hello!

We are a small company and we would like to use a combination of Free and Professional licenses for our computers. We have already purchased a couple of Pro licenses for testing.

On our account page we can assign the two licenses to specific e-mails and there is also a free license assigned to the account owner's e-mail.

For the sake of centralized management, we would like to add and distribute additional free licenses to some of our users but there is no option to do so.

Can you please advise how can we achieve that?

Thank you in advance.
John
