[Dx4win] Group names

[Mm0eax at aol.com]

Hi All 
    Using version 7.01, im attempting to split my log into  my 2 callsigns 
MM3EAX was my first callsign with 1700 qso's all after that was  with MM0EAX up 
too 12 000+
 
Following the help file i can't get this done :-( 
 
My idea is to name the groups MM3EAX and MM0EAX so that i can select a  group 
print and the qsl label should print the appropriate label with correct  
callsign, so i dont have to change the callsign in prefrences/rep/lab.
 
Is this possible or have i missed the point? Any how as i follow the help  
file and create a group name all i get is a blank logpage??
 
Any help please???
