Add the Possibility of Page Grouping

[Trodrige]

Description
How can we add the possibility of creating a PDF with 15 pages, say, with all the pages numbered from 1 to 5?

So, we have a single PDF file that is generated with 15 pages, but the pages are numbered based on particular criteria (the value of a variable). This is particularly useful when you have to do this for pdf files that have many pages. If it's just a tiny file then we can always create them separately and join them somehow.

Example
For example, we have a list of footballers in the USA from 3 states Ohio, Texas, and Florida. We've listed these footballers in order of their states. We want all the pages carrying Ohio players to be numbered from 1 to *, those for Texas 1 to *, etc, but all the 3 lists should be generated as one PDF. The variable here is the state!

So if each state has players which can fill up 5 pages, then we'll have a 15-page pdf number 1-5 for Ohio, 1-5 for Texas, and 1-5 for Florida.

I would be happy to explain any doubts and look at any questions 😎

wkhtmltopdf is to make pdf's from html not for grouping PDF pages. If you want that then you are better of with qpdf --> https://qpdf.readthedocs.io/en/stable/
