add current node under a specific menu-item.

Hi,

I need to add a certain custom breadcrumbtrail to a specific node, which is relative to a certain breadcrumb-trail. For example:
Existing breadcrumb: home/cms
With my addition: home/cms/outstanding/drupal 6
Standard: home/outstanding/drupal 6

So I generate the breadcrumb 'outstanding/drupal 6', but how can I "hang" this point under the cms-menuitem.

And additionally I want to highlight a primary-menu-item in the above example 'cms'.

Thanks for your help.
