Installer Choices for anything but the OS w/ InstaUp2Date

Hey folks, Does anyone have installer choices working in an InstaUp2Date work flow for other installs besides the OS? I used to be able to throw the mpkg install for Office or iLife in a dmg with the xml file that had the choices I wanted applied, but that's not working now. I'll be diving through the code for clues as well and will report back if I find anything. Thanks, Allister
