Synchronies Custom Properties

Is there any way to synchronies the custom properties betweenthe a model file and a drawing file?

We use \$PRPSHEET:{DESCRIPTION} in our drawing title block to getinformation from the model.

But we have to manually update the description in the drawingproperties.

We have several properties we would like to keep in sync betweenthe two files.

I started to look at the Property Tab Builder but that seemslimited. I also can't seem to find and help written for theprogram.

I'm also having a hard time finding the format/syntax for using theproperties defined.
