Problem:
I want to make a content control that says a recipients name, (John Doe) and have it populated throughout my document. The tricky part is this: I want to be able to change "John Doe" in any one of the recipient name content controls that I choose and have it populate all the others. In other words, I don't want to have a single "parent" content control, I want all of them to control the text within each other.

Where to find example of solution:
If you download the word template called Proposal For Small Business you can see that they have these specific content controls that I would like to set up.

Thank you in advance for all help.
