If you'd like to remove all the coverage items in a section, go to the Overview page and click on the three dots menu and then 'Remove from report'.

Then confirm that your clips will be removed from the section and any slides will be permanently deleted.

Or when you're inside a section click on the 'select all' button or select the clips you wish to remove and you can then remove the clips from a section. This will still leave the blank section afterwards.

Yes. Any items you remove from a report will still be saved in the Coverage Vault page, which stores a record of all the coverage you've added to your account.

Here I have searched for the publication name and date range to find the items I'm looking for. You can search by publication, coverage type, by report, folder or over a date range...

Next, select the items you want to add to a book and click add selection to existing book.

Then select the book.

And finally select a section in that book, or just add to the default coverage section.
