Custom group access that works all the way

[mopa]

It would be nice if it was possible to edit what contest a user should be able to see ie. if you:

Create a new user group.
Make only one department available under that group.
create a new user with access to only that user group.

Example:
I create a usergroup called "coca cola" and make the department Coca cola available under this group.
I also have a department called Sprite, but I don't want the new user to see that department, so I only make Coca Cola available.
I also make sure that Tickets is the only thing that this user should have access to.

When logging in with this user I only see the department Coca Cola... and I only have access to Tickets... So far so good.

But if there are any filters and labels I can also see these and further more if I click them I can see tickets from other departments.
If I want to create a new ticket I can choose from all the available departments and not only Coca Cola.
If I click report I also get reports of all the departments etc. etc.

It would be nice if I make a group available for only one user and one department etc. It is only those creterias that is available.

Maybe something for Kayako 4?
