After reading only your title, I quickly answered "you can use MATLAB Schemer". Then I read the full text of your post. :-)
I kinda doubt that MathWorks is working on this. If there is something specific you want that is missing from MATLAB Schemer, I think your better bet would be to edit that yourself, or post a request to the FEX. Scott is actively responding to comments on the FEX, so maybe you have a chance?
