Customizations with Autoblog

I am looking for customizations with the Autoblog plugin v 3.5. These customizations are as follows:

1. Add specific content after each post title.
e.g. If the feed was pulled up from a blog "ABC", I want my new post title to say
"This is the original title - via ABC"
Obviously, I want to vary the suffix based on the feed ID, feed ID 1 will say ABC, feed 2 will say DEF, etc.

2. I want to add custom fields indicating the article source, e.g. as "Engadget", maybe in the form of a custom field for each feed.

Can this be done using some hook, etc or do we need to hack through the code?
