aggregator user favorite drupal6

Asking for a 'lil help discovering if a module or easy hack exists to allow users to 'favorite' or copy the content of a specific aggregator feed item to another node for their later use.

I did the standard google and drupalmodule searches and came up with nothing but possible implementations in drupal 7 (where I am using 6). I did find one module that "promotes" items hand-picked by an administrator to copy to nodes (I suppose like slashdot admin might) http://drupal.org/project/aggregator_promote but I'm looking for user favorites to be stored privately for their own reference.
