We use the same file format EVERY time we upload files (it's how they come down from our web site). But we have to re-link the columns to the fields (match/don't-match/re-match) every time we upload. It seems that this should be a setting that I can save (or that saves the previous alignment automatically and has to be changed BACK if we alter our format in future) for all uploads going forward. It's not hugely time consuming, but it's still pretty annoying - and should be a pretty simple fix. Thanks.
