Marking a form as 'done'?

Marking a form as 'done'?

Hi!

I've got a form that staff fill in when moving stock from location to location. I see the entries they've sent across and I input them into my stock control system.

Is there a way to mark a form as 'done'? So that I know which entries I've input, and which I've still to do?

At the moment, I'm using a hidden check box that I can make true/false, but I have to edit the entry to mark the check box.

Any ideas would be much appreciated.

Thanks!
Ronnie
