The paste option 'Keep Source Formatting' worked!
Here's what I was trying to do: insert a set of slides from one presentation (source) into another (target) while preserving the formatting of the slides from the source. The problem I was experiencing was when I chose 'New Slide/Reuse Slides...' it would insert all the source slides but use the target format, which isn't what I wanted.
So here's what I did:
- Open target presentation
- Open source presentation
- Copy first slide from source presentation
- Paste into target presentation where desired, using the 'Keep Source Formatting' option (you have to use the Paste drop-down from the ribbon bar on the Home ribbon)
- Choose 'New Slide/Reuse Slides...'
- Choose the source presentation
- All the slides will be inserted into the target and preserving the source presentation format
I agree I liked how it worked better prior to the 2016 version, but at least we can recover this functionality!
