How I can help to add support for Visio Stencils (.vss/.vssx) and Templates (.vst/vstx).

I know that there is a library developed to import visio stencils (libvisio), but how can I ask to LO community for develope the support that make this library available for use with LibreOffice draw and add the images to the gallery?.

Is there a wishlist anywhere, and if there is not in the roadmap, how can I donate my own time, developing this functionality with the LO team?.
