Welcome, that is quite a coincidence !
I have just been testing this with a G9 owner who is using Eye-fi cards for a time-lapse that could last up to a year.
It will be released within a few days but if you wish to try it now contact me with an email address.
Incidentally, you are mixing-up focus and zoom .. but you can save and restore both.
Also, you can only set focus to a whole number of mm.
At longer distances the focus reported by the camera may not match exactly to the mm for all practical purposes it will be correct.
