well i don't know exactly how your 2 voices are mixed in your lefthand.
I imagine that is something like that
    << \leftOne \\ \leftTwo >>
So i think that including a clef change in either on one voice would do 
the trick

  (rm 'leftOne 7 #{ \clef "bass" #})
or
  (rm 'leftTwo 7 #{ \clef "bass" #})

(Sorry, i am not at home for 2 days, i cannot test)

If the insertion is in bar 5 for example :
  (rm '(leftOne leftTwo) 5 #{ \stemDown #})
Or also
  (rm '(leftOne leftTwo) 5 stemDown) ; should work

You can have articulations pattern (copyArticulation.ly)

  arti = { 16( 16) 8-. 8-. }
  ...
  (rm 'instru 15 (ca arti #{ c d e f g a b c #}))
