Sony A7S - Electronic Shutter (stills) via Remote App?

[KrisAK]

Can anyone verify that the silent electronic shutter on the A7S is (or is not) available via Sony's Smart Remote Control app?

 

I'm hoping the camera could do double duty for both stills and video, and the silent shutter is a big draw, particularly for up-close (and therefore remotely controlled) wildlife shots. 

 

I've done this sort of thing with a blimped DSLR (tupperware and memory foam), which is awkward in the extreme. The A7S sounds perfect, but I've read that operating the thing in silent mode isn't possible via remote. Is that true?

 

Thanks so much.
