Multiple headers as "filename"

[awilliam91]

Is it possible to concatenate multiple header to create a filename to be add in the config.yaml?

I have tried to add them separate by space but it doesnt work:

export_options:
export_path:
timezone:
filename: f3245d46-ea77-11e1-aff1-0800200c9a66 f3245d42-ea77-11e1-aff1-0800200c9a66

I am trying to get "Audit ID" and "Conducted on" combined as filename when exporting to PDF.

Thanks in advance!
