cross-ref account <-> account nr. (ofx)

[gikotim at bluemail.ch]

I must have messed up my accounts!
When I import a ofx-file the account from which the transaction comes from
is automaticaly selected, right? The very first time a new account appears
in an ofx-file a window pops up and asks for selecting an existing account.
But how can I change this reference later on? It looks like I've made a mistake
at that time. Now it put the transactions on the wrong account!

cheers
