Odum has received requests for customization of the Shibboleth target attribute, hopefully per institution, on behalf of Carleton College, Emory University, and UNC-CH/Odum itself. The idea might be to parse the entityID from a given Shib user's login data, 1) prefer an existing redirectPage, 2) search for a stored URL or Dataverse alias in say a lookup table, or 3) fail/default to the root Dataverse. I had been bumping this in #1551 but its scope is narrower.
