[Dx4win] Callsign Alert

[wo2n]

Seems like there is NOT enough room to add the necessaary call sign alerts. 
Like the group at YU8/.
Is there a way to get all the callsigns in the Callsign Alert box under 
Prefrences? I'm of room ver5.2
I want to add 6 callsigns (YU8/ ) and of cause VP6DX. Any work arounds, or 
fixes?
Thanks, 73, gl Bernie/WO2N
