webadi content restricted to one corporate asset book

When generating a layout in webadi and using a content to populate the spreadsheet, is there a way to just pull data for a specific corporate asset book?  I am trying to create a mass additions spreadsheet and it is pulling data from all corporate asset books.  I am creating the spreadsheet for a unique corporate asset book but it pulls data for all books.  I don't see where i can code the content to just pull data for a specific asset book.
