Being able to edit or remove lines from Payment import without having to restart

Currently when doing a payment import if you have an error in your file, or potentially someone who is included on the file who isnt in the pay run, there is no way to edit the information on the screen. You have to edit the file, then restart the import.

It would be a good "quality of life" improvement to be able to edit a figure which is displayed. Or to be able to delete a line from the data.

Possibly add an exclude from import tickbox?
