Customer interface: State alias

[gambas]

Hello,

I would like to allow our customers to use the Customer interface.
The problem is that the State of the ticket is displayed. My problem is that all the States are displayed.
I would like to only have 2 States displayed in the customer interface:
1) "Close" when the ticket is "closed successful" or "closed unsuccessful"
2) "Open" for all the other states

The reason is that I do not want to show them that the ticket is for instance in "Pending reminder".

I'd need to have this kind of alias in all the page accesible through the customer interface (i.e.: ticket view page, search page, search result page).

I do not find a solution....

Thank you for your help!
