Is anyone showing ECN approval on face of Drawing?

Greetings,

I am looking to show the Windchill ECN information in a table on the CAD drawing automatically.  We need to show the approval date and perhaps the description of the change in the revision block of a drawing.

My initial thought was to have the ECN workflow pass the ECN information into the EPM document attribute after the approval task.  Of course the EPM attribute would be designated or mapped to a property or parameter in the CAD file.  When the drawing gets published on the state change, the table would update accordingly.

Is anyone doing something like this or have a better idea?

Thanks in advance.
