I have a section of pages on our site (so a parent page with many child pages).  In the past an administrator for the whole site was maintaining these pages, so no extra permissions needed to be set.  She now wants to delegate edit right to just this section to someone else (we don't want this person to be an admin on the site).  So we created a role for her and set that role to have edit rights on the page and copied permissions to decendents.  This is great for page security.  She can now add new modules.  But the permissions do not go to the modules on the pages.  Her primary purpose is going to be to edit all the existing modules.  Am I missing how to do this, or do we literally have to open every page and click on settings for every module (several modules per page) to give her edit rights?
