Autoblog Mapping to Custom Fields

Hey guys, I think it'd be hugely helpful if the autoblog plugin came with the ability to map data to specific custom fields. For starters, maybe the custom fields that are already created (original_feed, original_feed_title, original_imported_time, and original_source) could be mapped to custom fields that already exist, or at least available to be globally renamed.

Eventually, it'd be sweet if Autoblog could parse a feed as well and allow for custom field mapping that way as well.

Thanks for your consideration.
