Style sheet outside of contribute website

Question

We use Contribute campus wide here at Smith College, but have
just started using more global css based style sheets. So while a
department might be at www.smith.edu/department/english/index.html,
the the style sheet is at www.smith.edu/css/global.css
How do I setup contribute cs3 to show only the styles in that
location to contribute publishers and writers?
One idea is to pop some kind of generic css file in each
department website location with an @import or something like that
to get the global css and then point contribute to that file. Would
that work?

Answer 1

Thanks. So I just can't choose a style sheet outside of the
contribute website no matter which role I try. some kind of css
file has to be in the website area that contribute can see if I
want to specify one. I could setup a copy of the global.css file
which will work for contribute users, but over time it will not
perfectly match global as it changes unless we ran some kind of
search and replace script every time we updated the global.css
file.
