It doesn't show in admin panel of drupal site.butI think you can use mcc module for create mailchimp api for gettingnode. when you disable this module its show list of mailchimp listall campaign which you created with specified filter.
you can also use mailchimp apifunction for campaigngetting list of campaign:
$q = mailchimp_get_api_object(); $result$campaigns = $q->listmailchimp_campaign_load_multiple(string apikey, struct filters, int start, int limit, string sort_field, string sort_dir);
