Script for multiple projects?

Hi there.

So I migrate between LiveXP and Win7PE, and one of the tools that I use adds a registry key to Windows. However, the registry for LiveXP and Win7PE is different, so I have to change the process every time I want to add said registry key. Is there a way inside the script to program a different [Process] function for both LiveXP and Win7PE, and even possibly branch out to doing so for other projects/versions of Windows depending on where it is needed?

Thanks in advance. Image may be NSFW.
