Option to automatically add all sites to a list for reports/maintenance tasks

Currently, when you want to include pages for reports or maintenance scheduler routines (etc.), it has to be done manually every time a new page is added. It would be cool to have an option to automatically include all available pages while also having the ability to statically exclude specific pages that should never be included. At the moment, it's very tedious and there's a high chance of forgetting to add newly created pages to the list.
