[DXBase] Deleted Countries

[Bill]

I noticed recently that DXBase had identified a couple of my 4W stations as
the Yemen 7O. 4W used to count as Yemen before 1990. I understand how this
might happen. I decided to fix this error by looking into the drop down
identifier in the country column. All I see are the current countries. Is
there a way to identify this as the deleted country so that it won't show
this country as worked when it was not?
