Not Creating New Posts if Title is the same

We have an Emergency Alert system that can create multiple RSS channels. I have gotten AutoBlog to import the feeds for the most part. I am having a couple of issues though. Because many of the messaging in the alert system are canned messages, the title of the message is very often the same title with different content. However, AutoBlog only has 2 options; either ignore duplicates (which apparently assumes a duplicate title is a duplicate post) or override the duplicate by changing the content if it is different. I want neither, I want it to create a new entry every time, based on a new timestamp (not just date because multiple messages with same title and content may happen in the same day).

The other thing that I can't get to work it the import image to featured image, nor the set default thumbnail from existing media library image.
