It's easy enough to display the current version (revision level and iteration) on a drawing. Typically you wouldn't have these values directly display in the history table because they will automatically change as the version of the model or drawing changes. We display the "live" version in the titleblock on the drawing, but everything in the history table is "dead" text. We don't want that changing automatically. I know of no way to get the history table to update automatically - primarily because there is no way to break the link between the previous "live data" when the new live data propogates through.
