Hi Instructional Designer

Yep keeping the shop clean is a nice thing to strive for, yet sometimes the means to do so are missing

So unfortunately, you can’t, unless you delete them insert them again, and still this is difficult, if 1 slides uses a layout, you cannot delete the master

Yet there is another possibility. Via PPT.

1. Create you masters in PPT and preserve them.

2. Create 1 slide

3. Import that 1 slide (thanks to preserving , your masters will be imported)

4. Assign the right layouts to your slides in SL

5. Un-tick the preserve flag of you now obsolete old SL master slide

6. Delete the obsolete SL master slides
