Hi bethkahrer,
You may be looking for 'versioned data' if you are looking into reconciling changes to a master/authoritative dataset.
It might not be possible in Collector (as I have not worked with Collector for some time now) but a possible workflow could be to:
- Create a versioned dataset and publish it as a feature service,
- Create a version for user editor (e.g. a version named: "EditorDataset") in your database,
- Create a web map with the EditorDataset versioned feature layer,
- Share the web map as a collector application.
From there, when edits come in, they can reconcile on the desktop or through a version management service.
Here are some links for working with versions on REST and Collector.

Good luck!
