Feeder ships from Denmark to England?

Danish emigrants who did not depart "direckte" on a transatlantic ship from Copenhagen to U.S. departed "indirekte", which I understand means other European ports. I know many probably took a train to Hamburg or Bremen, but were there feeder ships that left from Copenhagen to Hull, England, just like feeder ships that departed from Oslo or Goteborg to Hull, England? Or did the ships from Oslo, Stavanger, or Goteborg stop first in Copenhagen and pick up Danish emigrants on the way to Hull? Are there any records that identify names and dates of feeder ships that departed from Copenhagen? Thanks. Jon
