How do you re-link a dimension line that is broken or linked to the wrong node?

We frequently find dimension lines in our schematics that are dynamic but have a broken link or are linked to a node on an unexpected object. How do we edit a dimension line and re-link it to the desired object or nodes? While the dimension line can be recreated, it is often frustrating because it still requires you to modify the font, position, and other attributes to the original. Thank you for any assistance.
