I have started to insert power point presentations into my class notebooks. I use the same presentation for a number of different classes and would like to have one "master copy" of the presentation which students cannot edit. I am currently having to upload the presentation to the files section of the class team. This means I have multiple copies of the same presentation. Is there any way of inserting a link to each class notebook which would point to the original uneditable copy in either Onedrive or Sharepoint?
