[Dx4win] Search for unconfirmed prefixes

[Joe Stepansky]

I always work some new prefixes in DX contests.  Right now it looks as 
though I have to go through the log manually, keeping an eye on the prefix 
window, to determine whether or not I've confirmed the prefix on a 
particular mode.  This isn't normally a problem, but when you work 1000+ 
QSOs in a weekend it can get time consuming.

Is there a way I can ask DX4Win to go through, say, my ARRL DX CW test QSOs 
and tell me which of those QSOs have callsign prefixes that I haven't yet 
confirmed on CW?  I've read a number of the questions regarding filtering 
but am not sure any of them pertain to this situation.
