Question: I'm using the Feeds module and entity references heavily on my site to add, update, and link content. Unfortunately, the data I'm using has a number of records that are named the same, which causes issues when matching Entity References through GUID. 

Is there a way to import entity reference fields through Feeds but using title and content-type instead?

Answer: 
I believe I've found an answer to this problem.

Using the Feeds Tamper module, I can add use the Entity Fields Query Finder plugin to lookup against any other field belonging to a particular content type.

In my case I'm saving the lookup key I need in a field, and then matching against that field & content type.

By default, there is no way to do that. 

So you have 2 choices:

A) Go by the referenced nid instead. 

B) Create a custom parser, see the [The developer's guide to Feeds](https://www.drupal.org/node/622700).
