move notes from g-clef to bass-clef

hi,
I `ve been recording some piano music with a midi keyboard in "grand staff".
Some chords I played with my left hand are now split up in G-clef and bass clef.
How can I move notes from the G-clef to the bass clef (don`t want to change the pitch, only i´n which clef its written)?
copying and inserting doesn`t work without deleting notes that are already there..
thanks alot for hints!
