There has been discussion of parameterized shared behaviours, but the
current implementation doesn't do that. I just added a feature request
for this outlining my thoughts on how it should work:
Please feel free to add comments to that item in the tracker. You can
add them here, but they'll likely get lost if you do. Adding them to
the tracker ensures that when we go to implement something your
comments are considered.
