AutoCAD Inventor :: Use Hole Table (or Similar) For Objects Without Centermarks?

I have a .stp file that I am trying to dimension on a drawing. There are about 100 or so lightening pockets that are all the same basic shape (a rectangle with a full round on the ends). As of now I have been manually making a table for each location. Is there a way to create something like a hole table to automatically capture the locations of the pockets and create a corresponding table? I know I can create a centermrk on the round portions to use with a hole table but I want to dimension from the center of the pockets for the table.
