So I have gtpedia and have the update. The thing is I would like to merge them for the complete thing. Is there a way to do this as having two different files makes me sad.
Yes, it's easy to merge PDF files (especially if you're using a Mac). Most popular PDF applications on Windows also support merging - check the documentation of your software for more information.
You could also just use an online tool like PDFMerge to combine the files. 👍
