KACE Product Support

I'm really frustrated. This isn't as easy as it seems, or I am not as smart as I once thought. I need to install a software package that has "additional" parameters, but am completely at a loss how to get KACE to install it as I need it. Here is the command, which works fine from a command line.

msiexec.exe /quiet /passive /i "c:\programdata\dell\kace\downloads\15529\SMART Education Software 2012.msi" INSTALL_NOTEBOOK=1 INSTALL_BOARD=1

I would love this to work from the Software Library portion of the Help Desk. How come I can't edit the full commandline from either the Software Library or the Inventory/Software page?
