Currently within our SP environment we have a script that runs whenever a site is created within our farm. Within each SP Site, a security feature has been added via script as well that outlines all user permissions.

Subsequent of this , we conduct quarterly audits of all of the security groups throughout all sites collections within SharePoint to ensure that all users that should have access , have it, and those that should be removed can be.  This process has some  SharePoint Designer workflow behind it presently, but much of the process is still done manually. We'd like to create a workflow via K2 throughout our environment for all sites that can be ran that would allow the site owners to access a link to security page created that lists all user permissions, and workflow would be set to alert necessary parties if access needs to be changed etc. Is there a way to create a master workflow that can be applied to all SP sites, or would we have to create wf, save as template and apply the workflow to each SP site individually?

Not sure if this is possible but thought I'd ask before committing to deploying this solution to all sites manually.
