How many theme licenses have we used?

Hi
I have been in touch with Envato and my question I believe has been re-directed to you.
Where can I see how many licenses are still available?
I work for a company that use Enfold for the websites we build.
We usually purchase a batch of say 10 or so in one go.
This reduces having to purchase a license each time we build a website.
This is works from our internal admin perspective but it is difficult to keep track of the licenses we have used.
Thank you if you can provide some help on this.

Best regards
Nick
