Describe the solution you'd like
I recently discovered the ggeffects package (by @strengejacke, so maybe you're the right person to address this), and still can't get my arms down - that's how useful it is. Especially test_predictions is a brilliant tool to make targeted tests of your predictions by the model. And essentially, I'd just love to get the output from test_predictions into a report sentence. It's great to get a long sentence about the model as a whole, but getting help to convey the comparisons that are targeting your specific question would be great!

How could we do it?
I'm not really aware of the inner workings of report, so I'll just leave it here.
