Can't you just copy the OGR issue to Adode Acrobat reader on your IPad and rename the issue from that point.
Or download to PDF , say 10 issues or more (one at a time, you just need a fast internet connection) of OGR on you desktop and save it to a lightening to USB memory stick. The memory sticks range from 32-128gb in size/memory. Plug that memory stick into your iPad and open PDF files, for easy reading. When you travel and do not have wifi etc.
