I want to have feature on hesk :
i have 2 category : Cat A and Cat B
1 user : User 1
When User 1 create a ticket , it will 2 option. If User 1 is member Cat A and Cat B. He will view this ticket (ticket created by himself).
But if User 1 is member Cat A, not Cat B. When he creates a ticket send to Cat B, he wont view this ticket (ticket created by himself)
