You can use copper shape on solder mask layer associated to pin.
That's the point.
I tried, but apparently it did not work. I draw a copper square on top solder mask but, generating gerber, it does not appear.
Maybe i am drawing shape or generating gerber in a wrong way...
(Has someone any suggestion? What do you mean by "associated to pin"?)
Thank you for your answer
I drew the copper square on solder mask layer (here on red), associating it with the pin. Here is the result:
(The copper square is half internal and half external on purpose, for testing what is going on)
Seems that it works only adding layer drawing part and not removing them.
The goal should be cover with solder an internal part of the central pin: I expected a white part on it, and it did not happen.
Thank you for your kind help.Luca
Snap it on the location you want (pin 9)
Modify the size
Select copper shape, RMB, select snap to
Exactly. Could you explain me how to do it?
(You can see here above my attempts).

It is a combination of PAD definition, associated copper shape on the mask layer and CAM settings.
PAD stack needs to define mask for all the pads except the center pad
The center pad will have no mask defined.
Draw copper polygon shape in the area where you want mask void.
CAM setting for mask should look like this.
Ok, i got it.
I was letting the drawing on the pin "solder mask top" layer so, generating CAM output, the central hole did not appear.
It the way you suggest, it works perfectly.
