Bulk Metadata Update

### The Problem

We often have requests from our editors to make updates to multiple datasets.
They have too many dataset to manually perform the update. The task is tedious, error prone and time consuming.
Editors are responsible for a large number of datasets. Often there are a number of points of contact that have moved. Editors need to change "points of contact" in complex ways-- sub sets of cases that make the task challenging.
Off the corder of my desk I have written scripts (and reused them) but these "need improvement"

### The idea

1. An app that allows editors to bulk update their records.
2. A ledger is kept of who did what.
3. Restore to previous states is a feature.
4. When updates are performed they do not overwhelm your installation.

### I'm wondering:

1. Has anyone already developed a solution. (yes I looked and did not find anything)
2. Would this be a useful contribution?
