There are many reports that can be edited and saved. When editing a report, just give it a name and click Save As.
You will be able to find all of these under the Saved Reports tab of the Reports page. Once there, you have the ability to group reports into folders. To create a new folder, click New Folder.
Once the folder has been saved, you can move existing reports under it. This can be done by clicking the Move button or drag and drop the report into the folder.
Once you are done using the report, you can choose to either Archive or Delete the report. All archived reports can then be found under the Archived Reports tab on the Reports landing page.
