Adding items to selection box manually

Hello,

Does anyone know if it is possible to add items to aPropertyManagerPageSelectionbox through the API, rather thaninteractively through the GUI. I basically want the selection boxto maintain its state between invocations of the property managerpage. I see a method to obtain the text of items in the selectionbox, but no method to add more items to the box.

Regards.
