Question on imported qfx files

[Drew Hope]

Windows XP, Gnucash Version:  2.2.0, r16304:16306 on 2007-07-14.

I currently import qfx files from two sources: a bank account and a credit
card.

I currently get two transactions for payments of the credit card from the
bank account, one from each import.  Is there a way to tell gnucash that
they're the same ends of different transactions easily?  At present I'm just
deleting one, but it would be nice if gnucash figured out that they were the
same (same date, same amount, etc).

Help?
