Purchase Order

Hi all,

when i write a PO the Contact Person(Attn) comes up as first line in
the Vendor address field...example:

Jim Johnson
XYZ Corporation
P.O. Box 12345
Chicago, IL 67890

How can i change it to be at least in the second line ?
The "Address Format" option under Vendor Maintenance doesnt have
the "Contact' as an available field.
