Can't be done, by design.  The "canonical" way to do this is to create
a script for an ExternalMethod and distribute it in the Extensions
directory of your product;  the site manager installs your product in
a given CMFSite by running this method.

Chris McDonough points out to me a feature of Zope Products:  any
'__methods__' in the product's '__init__' are made implicitly available
to all folders;  one might leverage this to make it possible to run the
installation without first creating an ExternalMethod object for each
add-on product.
