10.1 Report List additions?

In 9.1 you could add custom reports to the Related Reports dropdown menu on the Part Details page. It looks like this is not supported in 10.1

From 10.1 Customizer's Guide

Report Selection List Customization Adding a custom action menu item under the ribbon toolbar is not currentlysupported. However, it is possible to add a menu item to the right-click contextmenus in the structure that can launch actions or other jsp pages (e.g., reports).

Has anybody found a way to overcome this limitation?
