I've been made as alternative contact for one license owner and I have been responding to ticket which the license owner or his staff submitted.

What I don't like is that my own tickets for my own board through the years are not separated from the tickets that the other license owner has submitted.

I would like to see that these tickets from these two different license owner being separated and have their own section.

That's because the tickets are in the client centre. You can't have two different client centres for the same email address, which is why the tickets are in the same place

Tickets are organized by client, not by license.

So, if you have two licenses yourself, you'll see all tickets for those licenses mixed together.
