Quicken downloading old, reconciled transactions from credit union

I see that San Diego County Credit Union is affected by the unable to connect error. Even worse however is when it does connect, it dupes transactions going back 3 months that have already been reconciled. Unfortunately, there is no way to mass delete all these "NEW" transactions from the download list. I'm having to spend as much time manually deleting these as I would keeping my bank accounts in a spreadsheet.
