Is there any way of displaying different helpdesk types on a per site level
 
e.g On one site I want the drop down menu to show
 
1). Order enquiry
2). General enquiry
3). Other
 
on the other site I want
 
1). Bulk Enquiry
2). International Enquiry
 
The choices are only relevant on each individual site so I need them to only show on each site.
 
Does any body know how to do this
