we got it to work with a formula node with the following formula

if (x>=167.5 && x<=202.5) y=180;
else if (x>=-157.5 && x<=-112.5) y=-135;
else if (x>=-112.6 && x<=-67.5) y=-90;
else if (x>=-67.6 && x<=-22.5) y=-45;
else if (x>=-22.6 && x<=22.5) y=0;
else if (x>=22.6 && x<=67.5) y=45;
else if (x>=67.6 && x<=112.5) y=90;
else if (x>=112.6 && x<=157.5) y=135;
else (y=180);
