I have a large legal document that several attorneys are working on. It has numerous exhibits to be attached and they are referenced in the document.

I want to be able to have the exhibit #s (i.e. Exhibit 1) to be set to change whenever an exhibit is added or removed. I have achieved this with the caption feature, but I need to be able to link certain exhibits to others (i.e. if exhibit 7 is referenced again in the document I don't want to use the caption feature to auto sequence the exhibit number, I want it to refer to the original exhibit 7). How do I achieve this?

Thanks in advance for your help!
