I am looking for a way to paste slides from one presentation in other
presentation as a link, so that slides edited in the source
destination will be updated in the presentation where this slide was
pasted as a link.
Does anyone know if and how it can be done.
Yes.
Suppose you have two presentations, SlideLibrary and Real.
SlideLibrary is ... well, the slide library, the file you want to pull the
links from. Real is the presentation you're working on now.
Open Real, put it in normal view.
Open SlideLibrary, put it in Slide Sorter view.
Click the slide you want to link, choose Edit, Copy or press Ctrl+C
Switch back to Real.
Insert a new blank slide.
Choose Edit, Paste Special.
Click Link and make sure PowerPoint Slide Object is selected in the list box
(it will be by default).
Click OK.
Scale the inserted object up to fill the frame.
Save Real and close it.
From now on, when you open Real, it'll check for updates to SlideLibrary slides
it links to and will update itself.
You can also doubleclick the linked slide from within Real to launch
SlideLibrary, edit the linked slide and save. Now it's updated in both
presentations.
Pay no attention to the man behind that John curtain. ;-)
