Allow us to index our own sources
I first posted this as a reply to someone else's idea, but thought it deserved its own post. I'd like to see sources become far more useful than they already are.
I'd like to see sources changed to handle both single-record and multi-record sources. Single-record sources are things like Burial Record. Multi-record sources are cemetery plot lists.
If we're uploading our own birth register, we should be able to index each record on that source (using the same indexing tool we volunteer our time to), and update our ancestor profiles in the same way we do when we're updating from a record in a FamilySearch source. Allow us to use those powerful tools on our own personalised sources.
Further, expand the above into a collaborative project. I'm sure there's plenty of duplicate scans being uploaded all over the place. If I upload Page 63 of Auckland Cemetery Register, and index the record relevant to my ancestor, and someone else uploads Page 88 of the same document, right now these are completely separate things. If we could merge these into one project, you'd get community driven indexing of catalogues that FamilySearch might not get on its own.
There's still a place for private sources, and just as you can mark memories private or public, you should be able to do the same to sources you add.
Imagine finding new hints for your ancestors because another user indexed their own source that your ancestor shows up on.
All the tools in this proposal are already here on FamilySearch in some form. I just propose using those features together in more ways.
