In LO Writer, how to set name from the database when merging and save as individual document?

[fdf]

Hello,
I am using LO 25.2.2.2
I am used to to merge either with data from Calc or Base, but only the simple way (clic on options.)
I am trying to do something I can’t find the option for: merging my data in individual document (easy up to here) but I would like the file name to be different for each of the file with using one field of the database for that.

Above is the screenshot of my current point. I guess that’s where I should define the field for the file name… as later I can only give a random name which will be added with a number.

From ask.libreoffice, I found that screenshot which seems to solve my question, but I can’t find how to reach it.

A bit more verbose than @PKG
If you select “print” from menu, icon, Ctrl+p LibreOffice will ask you, if you wish to create a serial document. If you select “yes” you will be presented, with the screen you search, where you can select the necessary rows and other options.

Compare here in chapter “form letter”

Thanks. Pretty synthetic answer, but that’s what I was looking for. I was focusing on the merging tools.
