Ordinate Dimensions in Section Views

Does anybody know if there is a way to add ordinate dimensions to a partial section view as shown in my attachment? Ideally, it would be nice to be able to link them to the main datum shown, but if there is another way to make them come out correctly without linking them that would work as well. The attached image is is a good reference of what I am trying to do, but my actual part is much more complicated, so this would go a long way to cleaning up the drawing.

Thanks,

Josh
