[Dx4win] CW DXCC dilemma

[Floyd Sense]

If you use DX4WIN for tracking DXCC totals, I wonder how you handle this
situation:

A DX station (new country) was worked in 1973 on 40M CW.  The station is
credited by ARRL for the mixed DXCC, but not CW DXCC as the cutoff for CW
DXCC is 1975.  So the question is: how to  mark the QSO so that DX4WIN shows
it as "checked" for Mixed DXCC, but not "checked" for CW DXCC?  I don't even
want it to show up in DX4WIN as confirmed for CW, or I won't get an accurate
spot color.  What to do?
