Is there a way to show if a document is signed in Daeja?

Is there a way to identify if a document has been digitally signed on Daeja? In a form of a button perhaps? For example, administrator users can have this button to view if the document is digitally signed. If they are not administrators, the button should be greyed out.

If nothing out of the box for this and customer wants to customize Daeja to read the property ‘DigSign’ in FileNet and if the value is either ‘true’ or ‘yes’, they want to display an icon somewhere to show that the document has been digitally signed. Could you point me to the documentation that can get me started on such a customization?
