ADHL + ADH Merger

Upload the cover letter (ADHL) and one or more affidavits (ADH). You'll get back a single PDF: the ADHL, then for each ADH the clean copy followed by a copy with a diagonal red COPY watermark on every page.

Each ADH gets a clean copy and a watermarked copy in the merged PDF, in upload order.
Optional. Defaults to the ADHL filename + "-merged.pdf". .pdf is added if you leave it off.
