[Dx4win] Question about Notes for this QSO field

[Jerry N9AW]

My question - is it possible to make a mass change to the "Notes for this
QSO" field?

Background
I have used the group field to indicate my operating location.  One was in
a campground where I had a seasonal for years.  There were others too.
 Anyway, I want to use the groups field in another way.   I can select the
qsos I want to change using the Filter process.  But then I would like to
insert some text into the Notes for this QSO field for this group of qsos.
 Is this possible short of manually entering each entry?
