is it possible to ask user a text, and create watermark with the answer?

I am using the action wizard combined with preflight profiles to make some arrangements in the pdf I get from my customers.

I usually create a watermark and introduce it without problems, but I would like to go further, introducing a code number that changes for every item as a watermark.

It would be interesting that Acrobat asked the user that code number, and acrobat put that information in the bottom-center or the existing page...

Is that possible with the action wizard, or should I look for information in the javascript forum?

Thanks and Kind Regards.
