I'm writing Google Apps script to export a G sheet to pdf, using this article as a basis.
In the list of options that get sent to the spreadsheet export service is "printtitle=true". If I use this then I get the spreadsheet name at the top of each page.
I would like to change that name, on the exported pdf, so that it includes the date, for example. I'm looking for some documentation on this but can't find it! Help would be appreciated.
