Is there a way to overlap two markers on the same legend label?

In the plot, I resort to

plot(x, y, 'bx' , 'DisplayName', 'Data label');
plot(x, y, 'bo' , 'HandleVisiblity');

In the legend, is there a way to show the two markers overlapped on top of each other as the marker/line type?

Reading How do I use custom markers for a line object in a MATLAB plot? makes me suspect it is probably not possible, but I thought I would ask just in case.
