Using Google Sheets and working on a script to make exporting (downloading) a PDF copy of a single sheet much easier. The end goal is to emulate the Download as... PDF, but click of a button and it's done, without having to go to the menu. Also uses a custom file name (which includes the date and time).
The question...
When exporting a sheet using a script, is there a way to customize the content of the headers? I know when doing it manually, I can customize what appears in the headers and footers, but what about a script to change the top (or bottom) left/center/right areas when exporting a PDF via script? I know I can optionally enable a title (printtitle=true) or sheet name (sheetnames=true), but I can't find anything to permit me to customize what appears.
What I would like is to have a custom name/string for the top left and top center, then the date and time in the top right.
