Multi User Colaboration Improvement

It would be very helpful if I could edit metadata, rate, cull, search, etc. photos on a shared collection with different accounts. I work at a church and we have a church owned account that uploads the photos then 2-3 other individuals who may rate, add keywords, edit, and export these photos to our website, social media, or just to share. It would be much easier if any team member could serve as a collection 'owner' and have the same permissions as the owner of the collection to edit metadata, etc. Currently it is very difficult to use Lightroom to find old photos when we are unable to remotely keyword or search the photo library.
