replicating a record

I was working yesterday around the sheets and I discover that a record outside the sheet is not showing the columns (and Devon software tells me this is not a bug: records have to be inside the sheet).
But I discover today that a record can be replicated outside the sheet! And this is a nice feature: I can mantain a sheet with a list of books (for example) using column like publication year, author, editor et ceteare, and build different group for each book containing reviews, inteview about the book, notes and the replica of the record corresponding to the book. So working in the group I have the record with info about the book, and using the sheet I have a list of all the books.
