This has also become a debilitating change for me.  Had you not broken the import in the previous edition, we would have never upgraded and now that I have upgraded, you've caused what used to be a couple hour process of importing transactions into a multi-day process of reconciliation from mistakes. 

This should be an emergency fix.  It isn't a feature request, it is a bug and a big bug.  Please get it fixed ASAP or we will also need to leave Quickbooks for a working software.
