The best way to submit wish list requests for future Vectorworks features or content is via the Wish List section of the Vectorworks Community Forum. The Forum is regularly attended by Vectorworks Inc staff who can follow-up on requests.
While Paxar can submit requests on your behalf, it tends to be best to submit them yourself using the link above. This is so that you can fully describe and elaborate on your request. Often times this makes for an even more robust and developed request, which ultimately benefits everyone.
Note: Before posting your request, search the Community Forum for what you are wanting. Another forum user may have already asked for what you want. If they have, you can "vote up" that user's request (using the arrows in the top left of the original post.)
