[Dx4win] Combining logs/groups/QSL etc??

[Vanderydt Theo]

Hi all,
Currently i have two logbooks. One major logbook and one smaller logbook 
containing qso's from OO/pfx.
I'd like to merge these two logbooks but i need to be able to somehow keep 
track of these qso from the smaller logbook. In order to print qsl labels 
seperately from the allready larger excisting logbook.
What/how should i do this? Give a group number to the smaller logbook? And 
how do i retrieve these data's again ones it is merged with the larger 
logbook? Do i need to change the rep/lab comments everytime for qsl labels?
Yes i have read the help file but it is way too complicated and not to the 
point.
Thanks in advance!
