Currently it looks like the provider needs to do a lot of URL linking in her showcase to get the Reviews set up. That makes sense for external websites.
It even makes sense for her to be able to highlight a couple or so reviews on eccie.
What I am recommending is a quick search button in the review box so that all the eccie reviews on that provider are available. The box looks like this now:
Reviews
ECCIE Review 1
ASPD Review 1, Review 2
TER Review 1, Review 2, Review 3
Other Review 1, Review 2, Review 3
