Format Painter in Rise?

There's no format painter in Rise. I suggest you create block templates that are formatted for the main kinds of blocks you want to use. Then you can insert those as needed (instead of the built-in blocks that need to be reformatted).

Here's the User Guide info about block templates:

I want a format painter on the rise text ribbon too!
