append to existing breadcrumb?

Hi -
I wonder if workflow_ng could be helpful with the job of prepending a new breadcrumb to an existing breadcrumb trail using the 'set breadcrumb' action?

Here's an issue I commented on (a patch for the custom_breadcrumbs module that did not work). I add the link here in case something in my description (or the proposed patch) there is useful in answering this question in the context of how workflow_ng might be able to do this instead: http://drupal.org/node/215497#comment-838519

Thanks in advance for looking into this
:)
