kideyse,
It can depend how the feature is integrated. We build ontop of the WTP editor framework, but there are many different points of contact that we may not use that the SEAM integration into WTP may use.
All I can share right now is that management is aware of how popular this request is, and is planning our internal development roadmap accordingly. I have no ETA or promised release date to share for SEAM support at this time though.
