I think you are referring to incremental parsing here.  Well, Bison
has nothing to support incremental parsing.  You still can try to do
things by hand, but you need to be brave.

Maybe start browsing at the Harmonia Project.  Try to find a
Ph.D. from `Wagner' (sorry, I don't remember his first name, but
additional keywords include `Harmonia' and `Ensemble'); it has quite
some information about IGLR (Incremental GLR parsing).
