See
https://www.gmayor.com/insert_content_control_addin.htm which makes the insertion of mapped content controls a breeze. Insert a mapped control and copy and paste it to all the other locations where you require the data. Anything you enter in one of them is repeated in the others.
My old friend Greg Maxey has produced
another version developed from this, which has even more facilities, but this one does all that is required by most users without unnecessary frills.
