Libreoffice writer increment number in text box using design mode

I would like to start my number from 10000 and when the user opens the PDF everytime, the textbox will auto-increment so starting from 10000 → 10001 → 10002 etc

Is this possible? Can someone help me on how to do this?

No. Not with PDF.

Can you recommend me other solutions to do this then?

An office document with a macro.
