NodeStream 7.x-2.0-rc5

I'm trying to put POLLS into the Regions (MAIN COLS # and ASIDE) But I can't add a TOPIC REGIONS taxonomy (vocabulary) to the POLL

I'm using this procedure in Drupal https://drupal.org/node/1886980 but Nodestream can't manage fields

How can add a vocabulary to a content type in NodeStream?

Thanks
