[Dx4win] Filter for LoTW!

[Jaime P.Ullívarri]

Hello all,
I would like to send my log for beta testing but I have a  problem as other
EA's.
My normal callsign is EA6NB but for 6M is EH6NB, as it is for all EA with 6m
license.
I have all my qso's in the same log (from 160 to 6m) in DX4win software.
I will have to send a separate log as EH6NB, not problem,
Filter-Selection-Export.
But how I export my log without 6M QSO's, as EA6NB?
There is an easier way from DX4win, as to export to EXCEL and filter the
QSO's there?
