Enhanced Messaging for Ignored Items in Import

Description of the enhancement required:

Improve the messaging around why things are ignored so that there is a full breakdown of the successes, ignores, and failures in an import. 

An example of the enhancement:

This could be full messaging upon completion of an import regarding the ignores.
For example, it could be a message that the list member was ignored because it was not a part of the list subset.

How would it help your business process:

It would help account for the entirety of the file that is imported so that we can fully understand what was successfully imported, what was ignored and why, and what has failed and why.
