Map Multiple Fields to Body? Append?

Hi,
I'm going to try to make generic a specific problem I'm having:

Here's the generic question: Is it possible, or might it be possible in the future, to map multiple feed fields to a single node field?

Here's my specific problem: the location field in an iCal feed is arbitrary text, so I can't map it with the Location mapper, so I'd like to append it (and maybe some other data in the iCal feed) to the bottom of the body. Can I do that?
