Export FX Rates

Hi All,

I am trying to create simple Extender rule to export only the AverateRate FX rates.  I saw this post: What is the most efficient method for exporting FX rates to a CSV file in OneStream? | OneStream Community  But this does them all.  Short of exporting to this file and creating another file from that one.  Does anyone know how I can filter the export to just get the Average Rates?

I see the variable xmlOptions.ExtractAllItems = True.  But if I set it to False, I don't see what options I have to filter to specific metadata. 

I'm open to exploring other options as well.

Thanks,

Scott
