Possible Conflict with Symlinked Directories

In doing my migration to WP with MZ just realized that MZ uses the media directory to output its CSS file. This seems to be a potential conflict with my setup.

Let me explain my setup. I'm migrating from a custom content management system to WP. I manage several sites on the same server. Since many of the sites share images, css, and functions, under each site's directory is a symlink directory pointing to a directory called "share," which includes three subdirectories, "images," "include," and "css." Each site has access to these files, and a change in one goes across all sites that use the applicable file. In my WP setup, I set the media directory as "/share/images" so that I can still share images across sites.

However I don't intend to style each site the same. If MZ is going to write its stylesheet from each site to my shared directory for all the sites, might this not cause a conflict? I still want to share images across sites. Is there an easy way to have MZ write its CSS files somewhere other than to my media directory?

Thanks,
