XYZ Math Surface, another parameterization of Boy's Surface

Hello,

"Add Mesh -> XYZ Math Surface" has one preset for Boy's Surface, but there are several, and they are all pretty cool shapes. Here are settings for one that I was exploring today. Can it be added to the plugin? Thank you,

X equation: 0.5 * (2 * f - g - h + 2*b*c * (g - h) + c*a*(f - h) + a*b*(g - f))
Y equation: (sqrt(3.0) / 2.0) * (g - h + (c*a * (h - f) + a*b * (g - f)))
Z equation: 0.125 * (a + b + c) * ((a + b + c) * 3 + 4 * (b - a) * (c - b) * (a - c))
