How to add action to “Model Structure Report” and “Family Table”

Hi,

I have created URLActionDelegate for my action and have code (Link) to be added in .xml file

If i add in "NavigationAndAction.xml" under any of the Navigation_Tree it does not gets rendered in

“Model Structure Report” and “Family Table”. But i am able to show in "Product Structure" which belong

to WTPart. As“Model Structure Report” and “Family Table”belongs to EPMDocument. In which .xml i should

add an entry to get action displayed in“Model Structure Report” and “Family Table”?

And as it is a template processed one it is difficult in finding definitions of actions.

Thanks
