Importing trial balance in the second year

[rduffy]

I setup the trial balance and mapped the accounts last year.  This year I would like to import the current year unadjusted balances.  When I go through the wizard to import it brings in all of import information and overrides everything I did last year.  I loose my mapping and AJEs.  How do I import just the updated amounts without loosing everything from the prior year?  I can hand key in my current year figures but with a large trial balance that takes a long time.
