The short answer is "NO"
The long answer is "YES" but only if you are a
very good coder and understand how animation behaviours work in code. For most people it's "NO" but for a good coder you can build new animations by adding behaviours and they will play in PowerPoint without the code. We have an Add In
TWEENY that builds a grow or shink
and rotate
and motion path animation. There are demos on the page.
