How can I get more than the 6 camera angle presets in movie mode (when you press TAB in build mode)??

I'm a researcher at Colorado State University. We in Cognitive Psychology use The Sims 2 as a VR world for our experiments. We put subjects in big houses full of rooms, then look at their memory. Each lot is fairly large: 16 rooms or so over 4 floors. Because we're not using the sims models, we just go into build mode, activate movie mode, and fly our subjects through.

I only have 6 presets to work with, which makes flying around... limited. Is there any way to add more of them? Can I somehow feed the game an x-y-z coordinate and get it to take me there? How about loading new presets into the 4-9 keys on the fly? Remember, I need to move the camera, not sims, and I'd really like to do it in build mode, if possible.

Thanks in advance for any help with this!
