SDL Project Automation API: Reference Files

Hi,

When using the SDL Project Automation API, I can specify references files.

However, the reference file(s) don't seem to be added to the target language LanguageFile.

When using the SDL Trados Studio, the reference file(s) are both included in the target language LanguageFile and physically copied to the project/target directory.

Is there a fix for this, or have I overlooked an obvious option?

Thanks in advance,

Samuel
