I'm not sure I'm asking this the right way, so if it's been posted before please point me in the right direction, but, I have a drawing of a sheet metal part where I use the Insert-->Model Items... to insert drawing dimensions.  I wanted to append the text "(TYP)" to a few of the dimensions, but the "Dimension Text" dialog box is greyed out. so I found the only way to do this was to check the "Override value:" checkbox.  Since the part is parametric, I didn't want to have to do this every time, so I added the text to the sketch dimensions hoping they would come in but they didn't.  Is there a way to do this, or are my only options to override the value, or add my own dimensions?

Here's the Sketch, and the drawing:
