Menupopup active/highlight position from serverside

In ZK 8.0.3.1, popupmenus can be opened or closed from server side.
However, there is no API to choose the current active position in the menu.

The attached example / fiddle shows the current workaround to open and select a position from server side using javascript evaluation.

It would be nice to have a simple server side API on menupopup such as:
myMenupopup.setActive(Int index);
