GL Entry data copied from previous document?

Hi Folks,

When entering the Manual Journal Entry, can we call upon a previous journal entry so that the line items and other details are automatically filled in as per that entry?

Account assignment model works but lets say a person doesn't have it setup and they want to put in the details in the GL entry screen from the previous GL document, would that be possible ? (something like how MIRO screen pulls up PO info. when entering the PO# ; if we can put the previous journal entry document number somewhere to pull up that document within a create new GL document screen)

Thanks
