Mapping Feed to Nodes with passing Feed title to each Node

Using the FeedApi with the Feed Element Mapper i import an rss feed and generate nodes for each feed item using the mapping function of feed element mapper.

I would like to "pass" on the Feed Title and Feed Description (NOT the feed ELEMENTS title or description) to each node created.

The end result would be e.g. having 10 nodes created from feed xyz.com.... each node (=feed element) would contain and additional field e.g. called "FEED TITLE" in this case filled with "xyz.com".

Is there any way to do this?

Any help would be great.
