Editing Multiple Address Book Contacts / Entourage 2008 v12.2.6

[Steven]

Greeting all:

As I doubt I am the first to ask, I have tried searching for an answer
but have been unsuccessful so here goes:

I have many individual contacts for people that all work at the same
company, address, phone number, etc. So what happens when the company
moves across town to a new address? Is there a way to change batch
edit EVERYONE's address at once or do I have to individually update
25+ names?

Thank you,
Steven
