Ledger sort of has that built in, actually, but it only works if you have a similar transaction in the past. For example, I can say this on the command line:

  $ ledger xact 11/5 mcd dinner 10.55

and ledger spits out

  2015/11/05 McDonald's
      Expenses:Food:Dinner          $10.55
      Liabilities:Credit Card

This falls down when you're traveling to new places, because in the command `mcd` is just a regex that matches on the payee.
