CCSTD attach_modified.jsp UI Customization

Tim__D

We have taken advantage of the new UI customization feature and added a custom column to all our paged lists displaying the value of an EA.

On the CCSTD "attach modified files" screen we want to do the same thing but this list does not appear to be available for customization using the IWOV UI.xml files.

In the actual file attach_modified.jsp is all the "widget" tag syntax which I have never dealt with. Anyone know where to look for info on how to customize this screen. All I want to do is add a custom column displying the value of an EA like I do everywhere else.
