[support] can i hook a hook?

[Larry Garfield]

Some hooks that offer definitions, like hook_menu(), will have a corresponding 
alter hook like hook_menu_alter().  There is no alter hook for hook_block(), 
though.  That said, there is an alter hook for all forms, hook_form_alter().  
So if you're manipulating a form you may be able to do so that way.
