Windows 7: Relocate WinRAR Context Menu (Context Menu Handlers)

I've done a bit of reading in the tutorials on how to make different customizations in the Context Menus. I've managed to make my own and everything is going fine.

The next step I'd like to take is to relocate the context menu handlers for WinRAR and WinZIP and put them in my custom menus.

I've edited the menus manually in the registry using the "SubCommands" item.



Is it possible to add a context menu handler to one of those custom sub menus?

EDIT: I have tried a few things. I poked around the "HKLM\SOFTWARE\Microsoft\Windows\Explorer\CommandStore\Shell\" key and noticed "DelegateExecute", and several other items that seemed pertinent. I tried creating "DelegateExecute" in various places within my custom commands using the CLSID values for WinRAR and WinZIP, and nothing seems to work. I'm guessing the custom menus is not meant for Context Menu Handlers?
