automatically dimensioning a complex chain

I was wondering if there is a way to automatically measure and dimension a complex chain, similiar to how the label line tool (found in the misc. dimension toolbar) works. It would kind of be like a combination of the measure length tool and the label line tool, except I wouldn't need the angle or bearing like the label line tool gives. I also would not need any extension lines or dimension lines, just the length. Maybe somebody has created a macro that can do this. Any help would be appreciated.
