How can we improve Microsoft Azure Data Lake?

Support 'dynamic' output file names in ADLA

When reading files, it's easy to read from files, using the wildcard characters and dynamic parts of the URI. (see the Month variable)
@mydata =
EXTRACT Customer string,
Active bool,
Month string
FROM @"/MySolution/Energy/InputFiles/{Month:*}.csv"
USING new USQLExtractors.CustomExtractor();

I als want to have this behavior at the output side. I want to split out by customer (and don't know these customer upfront)
OUTPUT @mydata
TO @"/MySolution/Energy/OutputFiles/{Customer:*}.csv"
USING Outputters.Text();

Please make this possible.
