This may be the same as the question posted by cheeves?
I have multiple PDF documents. I want to assemble them into a single PDF document and be able to specify that some of the assembled documents generate sub-sections of others.
So, with four documents, Doc1.pdf, Doc2.pdf, Doc3.pdf and Doc4.pdf I want to assemble such that
Doc1 generates Section 1
Doc2 generates Section 1.1
Doc3 generates Section 1.2
Doc4 generates Section 1.2.1
