Is it possible to reduce sketch text line spacing less than SW default?

The sketch text dialog allows you to adjust line spacing (as does the document properties). However, when you set it to zero the spacing is still rather large, in my case about .107" for a .160" font height. I want to reduce this further to more closely match what our engraving machine does. However, SW will not allow a value less than zero. I could separate the text into individual lines, but I would rather not to that, nor do I want to reduce the text height.

TIA!
