If you go onto the insert tab on word, then go to quick parts, document property and choose abstract, then go onto the developer tab an go onto the properties of it and change the title and tag to something meaningful and then copy and paste that box where you need it and they will be linked, that is how I did it. I wasn't sure if you could do it another way though as the building block gallery has quick parts when you use that, haven't used it my self though so not sure.
