Just a small comment: I do that by just adding the relevant VAC PDFs to the Briefing Pack PDF by hand on the iPad. As I also include feasible alternates quite frequently, adding departure and destination would have no real benefit for me. I would rather prefer to have an option in the PDF context menu to "Append This PDF to Saved PDF" instead of the simple 'Save to Files' - omitting the step to merge the PDF in Files.app.
