I just tried making a rectangle of solder mask -- that's out.

This is in the manual:

  Pad [rX1 rY1 rX2 rY2 Thickness Clearance Mask "Name" "Number" SFlags]
  Pad (rX1 rY1 rX2 rY2 Thickness Clearance Mask "Name" "Number" NFlags)
  Pad (aX1 aY1 aX2 aY2 Thickness "Name" "Number" NFlags)
  Pad (aX1 aY1 aX2 aY2 Thickness "Name" NFlags)
 
          ©
rX1 rY1 rX2 rY2
            Coordinates of the endpoints of the pad, relative to the element’s 
mark. Note
            that the copper extends beyond these coordinates by half the 
thickness. To
            make a square or round pad, specify the same coordinate twice.
aX1 aY1 aX2 aY2
            Same, but absolute coordinates of the endpoints of the pad.
Thickness width of the pad.
Clearance  add to thickness to get clearance width.
Mask       width of solder mask opening.
Name       name of pin
Number     number of pin
SFlags     symbolic or numerical flags
NFlags     numerical flags only


Can you look at your element file for the fiducial and change the mask flag and 
see what happens?

This would give solder mask no opening, so fiducial covered with....
and also fiducial no stencil opening, so not pasted on...

Is you soldermask clear enough?

Does this need to be a feature?
