[Plugin: Ultimate Taxonomy Manager] Default value

Hi, great work on the plugin so far.
I have just added a new custom drop down field to one of my taxonomies. Is there a quick way to add a default value to all of the current terms, either when creating a custom field or afterwards? WordPress does not include a Bulk Edit option on taxonomies, or else that would solve my problem.

Thanks.
