[Dx4win] Ending Country Callsign Date

[STU]

When there is a certain callsign in the country file that is no longer
active how can I put an ending date for that specific callsign only, not the
country?

IE. VP8ROT that was spotted recently is NOT on South Georgia any longer.
Under the country calls it has a starting date for VP8ROT but no place for
an ending date. Do I just delete the callsign entirely or is there some way
to put an ending date for that particular callsign?

I thought I recalled under the call tab there was a start and end for each
entry. Can't seem to see it. Just under mapping has start and end dates.

What am I missing?

Thanks,  73,STU (W6TA)
