[feature suggestion] Hidden entries in Start menu

[Gregory]

I wish I can create hidden entries in Start Menu.
Usage:

1) Suppose I want to define hotkey for external program (with cm_usermenuxx command) but I don't want to see that program in Start Menu

2) Suppose I want to create separate menu for external programs

The rule may be something like this: not to display entries whose titles starting with % (or other symbol)

I know that all this can be done manually by restricting Start Menu and creating another menu with choosen commands from it, but with proposed feature that would be a lot easier.
