We have that feature on our TODO list but for now I can't say when we can implement that feature.
if I can give some advice:
- It would be very useful to be able to merge multiple files and insert page numbering
- In some cases it would be useful that the numbering could start from a number other than 1
Page numbers can be added with the PDF24 Creator 8.1.0. The Save As dialog contains a new section under den PDF output filter and there you can configure the page numbers.
