Can I use Acrobat SDK to add a sub-menu in Content Panel context menu?

[chingy83881432]

Is there any Acrobat SDK I can use to add a sub-menu in an existing Acrobat context menu?  For example, the Content panel can be brought up by Acrobat's View->Show/Hide->Navigation Panes->Content.  On the content panel, one can select 1 or more items, right-click brings up a context menu.  If I want to add a custom menu option to allow me to access the selected object(s) and perform my own custom actions, is it possible and if so, how do I do that?  See the menu in the screenshots below.  - Thanks!

Thanks.

Unfortunately, not. That menu cannot be changed.

That's too bad.  It would have saved me some work.  Thanks.
