[Dx4win] Clearing QSL date field?

[Juha Rantanen]

I would like to re-print a bunch of labels I printed out 18.12.2005. 
Every QSO has QSL date set as 18.12.2005. I can do easy F8 search to 
locate them but is there a way to clear the QSL date field without 
having to do it one-by-one. There isn't such option in Multiple QSOs 
operations.
