Subtract all values from one structure from another structure

I have two structures with various different sections of a dataset. Both structures are identically sized - they are set up exactly the same, with each array within the structure the same length as the corresponding array in the other structure. Is there any way to subtract one structure from another, to create a new strucure, so the values in each corresponding array are subtracting from each other. I have not been able to figure out a way of doing this - can it be done? Or will I have to extract these values from the structure first?

e.g.

%% create the structure
data.x=(0:5);
data.y=(0:3:33);
data1.x=(0:2:10);
data1.y=(0:6:66)

Here, I would want the following to be done:

data.x - data1.x = data2.x

data.y - data1.y = data2.y

Is this possible? Or do I need to take a different approach?

The only way I can think of is looping through the fields:

%% create the structure
data.x=(0:5);
data.y=(0:3:33);
data1.x=(0:2:10);
data1.y=(0:6:66);

data2 = data;
fields = fieldnames(data);
for n=1:numel(fields)
    data2.(fields{n}) = data.(fields{n}) - data1.(fields{n});
end
disp(data2)

    x: [0 -1 -2 -3 -4 -5]
    y: [0 -3 -6 -9 -12 -15 -18 -21 -24 -27 -30 -33]
