Import code coverage results from other tools?

Is it possible to import code coverage results from any other formats? In addition to our C# tests, we also have some C unit tests for our embedded code which is compiled with the IAR Compiler and coverage results are collected with their C-SPY tool. We would love to be able to import these coverage results so we can use the same tool to report. We could write a script to convert to an XML format if necessary.

Thanks.
