Update Multiple DB records in one table with one form

I am developing an onine proofing system that will display a number of images, and then allow the customer to approve each image, as well as provide comments.

I currently have a table setup with the various elements (an image that dynamically gets its name, details about the image, and the neccessary form fields). See This Image for the layout

I would then apply a repeat region (the number of signs would vary), and like to update all the records with the customer's comments and approval with one form. How is this done? I have downloaded a trial of the developers toolkit, but the documentation is horrible. I would be willing to buy an extension that will allow this, if one exists.
