[Dx4win] Settings filters & printing labels for new mode/countries

[Larry Gauthier (K8UT)]

Last weekend I operated a RTTY contest and used N1MM Logger as my logbook. 
After the contest, I exported/imported the QSOs into DX4WIN. I would now 
like to set label = "Y" and print labels for all QSOs where that DXCC entity 
has not been confirmed in RTTY.

Is there a way to set a filter for this type of query? or do I just have to 
manually crawl through 400+ QSOs?

Thanks in advance for any advice,
