Editorial Calendar

Hello - I am looking into building out an overview Editorial Calendar to pull from each of my 12 program’s boards and Media Relations board. However, I am unable to share this calendar with others because they don’t have access to each of the boards I’m trying to pull from. Does anyone have a work around? Again, I have perhaps 15 boards I need to pull from to gain an overall Editorial Calendar view for what is launching when. I appreciate any help you may provide.
