You can already do this. As long as the previous host left them a review.
When you click their profile you see the places they have stayed and the reviews hosts left them right?
For example your guest is called 'Angela' and on her profile she has a review from 'Bob' saying she was 'ok, clean welcome back' (or whatever)
You click on Bob's profile you can see his listings... you check which she stayed at and click it.
On 'Bob's' listing you can serch his review's there's a little box at the top of the reviews, so type in 'Angela' in the box, and her review will pop up.
If the review was fairly recent since one of the updates, then the star rating she gave will be visable as well.
It really doesnt take long, a few clicks, type (or copy and paste) her name in the search box.
Persumably the seacrh box is to look for reviews and guest feedback on keywords like 'location' but it works fine for this too.
