Zoho Desk: I want to allow certain CLIENT PERSON not company to view their OWN tickets

I want to allow certain CLIENT PERSON not company to view their OWN tickets.  I know how to allow all and maybe to view the whole company if I enable some global settings.  But would like to allow just 1 Person to view his own tickets.

Is this possible???

Thanks
