Shortcut for epeated chords?

[papa.eric]

Is there a shortcut for writing repeated chords? For example instead of
<c e g b c'>16 <c e g b c'> <c e g b c'> <c e g b c'>
<d f a c c'>16 <d f a c c'>8 <d f a c c'>16
etc...

I would like a token meaning "the last chord (pitches between < and >) once 
again".

If there is nothing, does the suggestion to use empty chords <> for this seem 
interesting?
(provided empty chords do not have any use, they are compiled but seem like 
skips?)
