We are using the ISO Drafting Standard and I'd like to tweak the hole callout that displays the quantity of holes slightly.

A call out for thirteen M6 Tapped holes is currently displaying as:

13 x M6x1.0 THRU ALL

I'd like to get rid of the space between the 13 and the x, and make the x upper case. Is there somplace in the calloutformat.txt file that controls this?
