We would like to consolidate & clean up the large # of lists we have in Constant Contact by exporting old lists to save off-line and then deleting them from CC. The trouble is, when we go back to a saved (sent) Campaign Eblast that may have used that deleted list, the list name has now disappeared from that eblast's list history (the half-dozen or more lists that this particular eblast may have been sent to). We would like to have a feature that retains those old lists in the history, in case we do marketing research or if we decide to resurrect an old list from our offline storage in order to resend a particular eblast.
