Beep after bracket/intervalometer with picoc?

[Marsu42]

I recently requested a feature http://www.magiclantern.fm/forum/index.php?topic=4612.0 and wonder if this is possible to script instead with the current api (I know it has beep()) ...

* trigger shooting with the currently set bracketing values, then beep
* trigger the intervalometer to shoot multiple consecutive brackets, then beep

And is it possible to set the bracket or intervalometer option values (like ev spacing or # of repeats) with picoc?
