What is the best method to have multiple sets of bound content control in a document

What is the best method to have multiple sets of bound content control in a document?



The top of the document that I am working on, is an executive summary. There is one column for requirements. (Requirements are determined by a decision tree that is not part of this document.) Each of the requirement determines how
or if a section of the document should be completed.

I have successfully bound the first group using the method shared by Paul.

What is the best method to apply to multiple groups of content controls?
