Borrowed content
Borrowing content allows you use the entire content of one tab and apply it to another tab. In this relationship, you would only need to update one source and the rest of the locations that borrow that content will also be updated. Examples of where borrowing content might be useful could include: sharing information between BA and BS pages, or sharing information between the Masters and Doctoral levels of the Guide.
For step-by-step instructions on how to insert borrowed content, please see this KB: Guide: Borrowing Content.
Reminder: borrowed content is different than shared content.
