I need to call out threaded features on drawings by designating the diameter as a decimal and not as a number:

.086-56 UNC-2B and not 2-56 UNC-2B,

.190-32 UNF-2A and not 10-32 UNF-2A, etc.

The SW default appears to be the latter format, instead of the decimal.  I've tried editing the calloutformat.txt file, and I see that some of the hole wizard attributes (e.g.. ) include an attribute for the nominal diameter, but I don't see one for the threads-per-inch.
