Hey @fran2344 thanks for the contribution! I think what I'm going to ask you to do is break up this PR into 3 different parts so the diff's are smaller and easier to review. Lets do an individual PR for, 1) The Proto changes, 2) the backend, 3) the frontend.

Breaking it up will be easier for the team to review and will be able to get the changes in faster.
