Show costom-field in a list of tickets


i want to display a custom-field value in a ticket’s list.

For example: I you click “newst unowned tickets” you get a list of tickets:

ID Subjet queue status Created
1 Sub 1 queue1 open 22 hours ago
2 Sub2 queue2 new 1 hour ago

I want to display also a costumfield:

ID Subject queue status Created Costum_Field_Name
… Value1
… Value2

Many thanks,
