Discovery Service and OrganizationDisplayName

[Dan McLaughlin]

I have a parent organization that handles Authentication for multiple
sub-organizations.  I want to be able to have the DS list all of the
sub-organizations in the DS drop-down list, but have them all refer
back to a single IdP entity.

I was told duplicating the IdP metadata and changing the
OrganizationDisplayName should work, but what I'm seeing is that the
Discovery Service detects the duplicate entity and just overwrites the
OrganizationDisplayName rather then create two entries in the
drop-down list.

Is this even possible without customizing the DS?

  <Organization>
    <OrganizationName xml:lang="en">Parent Org</OrganizationName>
    <OrganizationDisplayName xml:lang="en">DisplayName
One</OrganizationDisplayName>
    <OrganizationDisplayName xml:lang="en">DisplayName
Two</OrganizationDisplayName>
    <OrganizationURL xml:lang="en">http://www.dot.state.tx.us/
    </OrganizationURL>
  </Organization>
