Multiple .MRR Files leading into same menu

I have multiple applications built from the ProjectWise SDK.

We now want to take a step back and try to better manage our menu options in ProjectWise that activates our utilities.

This has been controlled with a single .MRR file.

However it has become a little tedious as of late because each time we update and Application we must also update the .MRR file.

We would prefer each application have its own .MRR file, and when ProjectWise reads the .MRR file, it adds the menu pick to an existing drop down menu.

In my attachment you can see I have two "TEST" Drop down menus. Is there a way I can get the options to flow into just a single "TEST" menu?

Thank you
