Hi Andrea,

In the example I showed, I set the block to an =ignoreheading= block by
using =C-c C-b i=.  This, as best I can tell, generates a block but comments
out the part which gives the block its title.  Doing this overrides the
"alertblock" heading, so I'm not entirely sure how to combine the two to do
what you are asking.
