Process Payment

[Maris]

I don't know how to process payments without using the special dialog  
window for this. Since I'm importing bank transaction data in regular  
intervals, I'd like to be able to "assign" or "tick" appropriate bank  
transactions entry as the payment for bill nnnn.
Currently I only know of using the special dialog window and then delete  
the imported entry. I'm using gnucash 2.4.5.
