Field, Object, Viewport, Standard Scale

[rkmcswain]

When you create a field to display the "standard scale" property of a viewport, is there any way to modify the default string of "Custom" that is displayed when the scale of the viewport does not match a scale in your standard scales list?

In other words, can you change the "Custom" to say "N.T.S." ?

is there a way to write a lisp that would grab the viewport scale, if it is set to custom, replace it with a string that says N.T.S.?

I thought I read somewhere that one of the newer versions of AutoCAD is supposed to have the ability for lisp to fill in a field. I could be mistaken.
