How to export DSI information with external review (Studio 2019)

Hi,

I'm using the text delimited filter to translate csv files where I have extracted a particular column containing contextual information as a comment in the document structure information (DSI).

I would like this information to be available to an external reviewer in Excel.

I can only export comments using the SDLXLIFF to Office Converter or Export for Bilingual Review but not the DSI information as created by the text delimited filter. Does anyone know how I could make the DSI information available to an external reviewer?

Thanks,

Daniel
