Its the age old question, "When are we going to get this feature....why hasn't that been put into this product.." and the common response I give is "Well have you asked for it?" and usually the answer is no. Although in all fairness it's never really been that obvious how it can be done.
My answer used to be "Please log your request using the product feedback page" (http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=1109794).
This is one area that Autodesk Product Managers keep tabs but in all fairness wasn't the easiest page to find.
If you 're a user of the Autodesk forums you may of noticed a change of late, which is the addition of IdeaStations. So you now have a relatively interactive way to log new feature requests. If an idea gets picked up for scoping then you'll see the status change from New Idea to Under Review, Accepted and so more depending on how succesful the request is.
