I have a list of people my company has already mailed letters to (about
500)
. I have another separate list of people that may or may not have been
mailed to from the first list. Is there a way to quickly creat a column
of
checkboxes and then somehow crossreference these people that have already
been mailed to (both list have account numbers) so that we can exclude
them
from our next mail out?
