Adding the Stack Advanced option to other decoration processes

We have a very unique product that we are selling using the DecoNetwork Platform. We use embroidery as the primary decoration process but this is limited to the fonts available for Japanese and Korean Hangul fonts which are very popular with our customers. Because of this, I was looking at mixing decoration processes so the customer can use the visual designer and view the over design using TTF for the Korean Hangul and Specific Katakana fonts. The one drawback to this is that the stack option or vertical direct is not available in any other decoration process that allows the use of TTF. Is this this something that can be added to other Decoration processes, or even better, add an embroidery font that will recognise Korean Hangul symbols.
