MFC Feature Pack - How to add accelerators without deleting user's customization

I want to add new accelerat开发者_开发百科ors to my MFC Feature Pack application. The problem is the app loads the accelerators already stored in the registry, thus disabling the new ones I've added. I know I could delete the Keyboard-# key in the registry, but that would delete any customization made to the accelerators by the user.

Is there any way to add the new accelerators to the ones posibly defined by the users?
