Scripting

I have my doubts as to whether this is possible, but there are some pretty smart people here, so I may as well ask.

Way before I started here, someone put some corporate macros in Normal.dot and distributed them.

Some of the macros are no longer valid, so I'd like to remove them, and add the proper ones to another .dot file that can be deployed/redeployed at will. Obviously I can't push out a replacement normal.dot

Is there any way to script a macro remove, or macro edit?

Thanks,

Steve
