How can I change the search report for the Organization Hierarchy component?

Summary:

Other workspace components have the option to change the search report. Can we change the search report for the Organization Hierarchy component?

Content (please ensure you mask any confidential information):

We give our customers an "authorization number" that we store in the orgs.login field. They use that to identify the site they belong to for purposes of support contract verification.

It's a lot easier to search by that number than the org name for us, since we have a lot of large corporation customers with similar site names and even multiple sites in the same city. I just cannot find a way to change the search report for that component.
