any method to edit office setup file?

I wonder how to edit setup file or other to change the install option for office2003, I don't need some component in office, and every time I have to disable it when I installed. Can I modify some file to do a pre-disable what I don't want.
For example:I don't need Alternative User Input, Microsoft Handwriting Component, how can I do when I click next to the customization step, they are already disabled.
