Excel XLSX Generation, ACS on IBM i, and 0-rows select-statement

I just changed some of my programs that generated CSV files (CPYTOSTMF and
so on) to get XLXS files using this Scott Forstie suggestion
Generating spreadsheet with SQL
(https://gist.github.com/forstie/2deda50658106461f650cd71917feff9)

Very good ... just a bit slowly for ACS job and java environment ... but it
works and i got my xlsx files

There only an annoying problem ... when my SQL statement returns 0 records
... ACS won't create the XLSX file.
Is there any setting to tell ACS

"Hey guy, don't worry about rows ... could you please give me back an xlsx
with my columns' headers?, thank you!"

maybe only in one-word parameter?


Thanks

Roberto
