Hi, Deepak.
Thanks for your detailed request.
TheĀ tribe_ext_pdf_tickets_file_name_prefix filter exists, as you said you’re already aware.
Could you please explain the use case for customizing the file name for each event (or were you thinking of customizing per ticket)?
I ask because I’m curious, but my first thought on this is that it wouldn’t work because of the way the extension looks for existing PDF files by the applicable name. It currently only supports a single string, which is filterable, but I’m concerned it could cost even more server resources to look up a variety of possible file name combinations.
