For small constellations, you can just specify the points manually.
Here’s an example for 16QAM. Just paste into the “Symbol Table” field in
the block properties. The dimension is 1.

[complex(3,3), complex(3,1), complex(1,3), complex(1,1), complex(3,-3),
complex(3,-1), complex(1,-3), complex(1,-1), complex(-3,3),
complex(-3,1), complex(-1,3), complex(-1,1), complex(-3,-3),
complex(-3,-1), complex(-1,-3), complex(-1,-1)]
