Control over vocabulary as the source for node breadcrumbs

Hi,

I installed CB in place of Taxonomy Breadcrumb, which was very modestly configurable. I hoped that my issue:
http://drupal.stackexchange.com/questions/19470/how-do-i-force-indicate-...
could be resolved with CB but somehow I cannot get the desired result.
In short words: a node has two term references from different vocabularies. Regardless how user reaches the node page, I want to have control over which vocabulary is the source for breadcrumbs.

Is is doable with 2.x-dev or is it a matter of a feature request?
