[WriteLog] Newbie-Changing DXCC entity

[K7FL@arrl.net (Dennis Ashworth)]

During the 10M contest, I worked WH0AAM/N  and Writelog populated the DXCC 
entity in the Country window as Mariana Is. - KH0. However, the station 
reported his location as OR (Oregon) which I entered in the QTH window. I 
initially thought I would add a /W7 to his call sign, but that could be 
considered a busted call. What's the correct method for adjusting entries 
like this????

Many thanks,
