Constellation HD Supersource

Does anyone have a solution for having no boarders for Supersource on Constellation HD switchers .. I am aware you can make back plates and insert windows over , I am looking for a solution for live custom boarders on the fly .. Its miss leading in the product description , it leads to believe that its an extra DVE built in , yet the DVE allows for boarders .. and Supersource does not .. Please correct this Blackmagic Design ..

Adding my call for a return of the Box Border feature of the SuperSource engines on the Constellation HD line. I had a job the other day where I had pre-made backgrounds for a side by side, and at the late minute, someone has a narrow slide deck. If I were using my PS4k, this would be no problem, I could even automate a change with Companion. With BMDs new "next gen" switcher line, my production is hobbled because I didn't have a narrow background.
Also, without borders in the SuperSource box elements, any animation of the layouts becomes impossible.
