Converting a ProE sketch to a font

Does anyone know how to do this?

Instead of using a sketch for a molded-in logo I want to use a font. This gives the ability to change (scale) the image after it's in the model. Also, I can prevent sombody from changing any of the numerous dimensions, as thereare none with a font. Another problem with using a sketch; I have one chance to get the scale right, if not you have to delete it and try again.

Thanks
