seperate a full 9-digit zip and add "-", possible?

[cvgreports]

here is my scenerio, I have a list of over 2,000 addresses. And at the end is the 9-digit zip code...(i.e 123456789) and what I want to do is seperate the last four digits and place a dash "-" after the first 5 digits. Is this possible?


Any help I would appreciate, thanks in advance!
