Question about Apple Dev Portal

I asked in a different place but haven't gotten any responses so I thought I would throw it in there also. I took over the responsibility of managing the dev portal for our company. Now one apple id is the 'team agent' for two dev programs (both ios) and when you sign in you get a page that asks you to select your team. Our main 'team' has run out of available devices and I need to add another 'team' or dev program. How do I do that so it is associated with the same apple id?

My second question is what is a team selection page....I haven't seen this before and can't find anything on this.

Thanks.

 

So...anyone know??
