I would do something like:

 - Customize 'full_metadata_edit' to add a text input field for adding
   "additional" subject keywords, , e.g.::

    <input type="text" name="added_subject:tokens">

 - Add a PythonScript to the skin, 'fixupSubject'::

     subject = []
     for subject_org in context.REQUEST.get( 'subject', () ):
         if subject_org:
             subject.append( subject_org )
     for subject_add in context.REQUEST.get( 'added_subject', () ):
         if subject_add:
             subject.append( subject_add )
     context.REQUEST.set( 'subject', subject )

   Note that this script also cleans out any unintended "empty"
   values.

 - Customize 'metadata_edit' to call the PythonScript before
   calling 'editMetdata'::

   
   <dtml-call fixupSubject>
   <dtml-call expr="editMetadata( ...
