[Dx4win] Changing DXCC Valid Status for a Bunch of QSO's

[Juha Rantanen]

I use group feature in my master log that includes all my QSO's. Recently I
uploaded my QSO's from my small holiday expedition to EA8 in to the master
log. Now Dx4win calculates all those QSO's also into my DXCC status which is
wrong. I know that going qso's one-by-one I could change the DXCC valid
status to invalid but I'd rather not to do it like that. Is there a way to
perform multiple QSO's operation that would change the DXCC status to
invalid for a selected bunch of QSO's? I still use the version 5.03.
