How can I change the linewidth in a pzmap?

I'm really sorry if this question is answered previously. I want to increase the linewidth in a pzmap, because I should create lots of pzmaps for students and the normal thickness of the "x"s and "o"s are to bad to see in a script. So i hoped i can use:

s = tf('s');

G=s+3/((s+4)*(s^2+1))

pzmap(G, 'K', 'LineWidth', 2 )

This isn't working. Can somebody help me?

This is one way

fig = figure();
ax = axes();
s = tf('s');
G=s+3/((s+4)*(s^2+1));
pzmap(ax, G);

l_zero = findall(ax, 'tag', 'PZ_Zero');
l_pole = findall(ax, 'tag', 'PZ_Pole');

l_zero.MarkerSize = 10;
l_pole.MarkerSize = 10;

l_zero.LineWidth = 2;
l_pole.LineWidth = 2;
