thanks for the hint. Splitting and merging is somewhat similar as splitting is typically done by creating a new document and importing the needed pages into the newly created document. Using the current code this might lead to duplicate resources. > >> # merging files (e.g. avoid duplicating resources) > > Sounds like the files are pretty similar, is this actually an overlay?

I haven’t decided yet if it will sit on top of COS or PD. Typically we do encourage people to use PD so I tend to start from there and dig down internally as needed.
