Easydiscuss for Help Desk

Hello, I'm currently using the outdated: Imaqma Help desk, and it has been discounted now.
so I'm really thinking to use Easy Discuss as help desk.

But the way I want it is to have it fully private.
each user will see and have access only to the ticket he submitted, so other users will not know or even be able to open other users tickets.

The same for Tech Support

Each tech support who is assigned to a category will be able to see what is happening on his category only.

So basically I do not want to use it as fourm.

Can I achieve that?

Thanks
