Hi,
I haven't stumbled across this yet in Opus, so I'm assuming it's not there ... If it is, please do let me know!
I have previously used a presentation program called Astound (now sadly defunct) which produced video output (now in XE, I gather) and also had a rather nice object replace feature.
So, you could within Astound:
- explore objects
- select any object (say a picture, logo, animation, button etc.) that you wanted to replace with a different one, and which might appear in numerous places throughout your publication
- choose a replacement object
- click to confirm
and viola, all instances of that object are instantly updated.
Saves hours, sometimes ....
