DSC-HX60 has enough control buttons, but none of them works

[Krabice]

Even though FocusBracket was intended for "better" cameras than mine, on my DSC-HX60 should it work also, but setting of start point and end point focus position should be done by back control wheel (or LEFT and RIGHT arrows, or T and W zoom lever) also, not only front JOG dial (as I suppose, because I can not move the point by no controls on my camera). If made this alternative control, users of compact cameras (DSC-HX60/HX60V/HX400/HX400V, maybe DSC-WX220/WX350) should use this very interesting tool also.
Would it be very difficult to add the possibility of control by the rear rotary controler for the users of cheaper cameras? Thank you.
