Tool changes and the Origin

Newbie, so please be gentle…

The free version of Fusion does not accommodate tool changes in a single post process dump… If I create two files, how would that work for tool changes? The two bits are different lengths. Is the origin preserved between processes? Even if I mark the center origin on the original stock, that mark would be gone after the first process. Even if Fusion accommodated this, is the difference in tool length automatically accounted for? Is there a way to load multiple process files into Luban so that it prompts for a tool change and then continues?
