Pro use-case - editing an entire book? OR at least...a single chapter?

So I'm still having the "Plus vs Pro" debate in a few text threads with friends...

& MOST of the posts in THIS sub have been devs explaining that Pro is a good ROI for them based on the complexity of coding they're asking it to do...

Here's my Q:

Has anyone ever used Pro to edit an entire book in one shot? Does that work?

With Plus, I have to edit each chapter, section by section...pretty much been that way from the beginning -

But I'm wondering if Pro ROIs for non-devs with the ability to say to it "write me a 5,000 word book chapter on XYZ in XYZ tone" ...

OR to be able to take a voice transcript that's, say, 30-40 min long, and turning THAT into a single book chapter in 1 shot...

As opposed to having to edit it piece by piece...

Any thoughts about whether Pro can actually do this?
