3D matrix fftshift on gpu

I have an 3D matrix 512*512*100. I want to apply fftshift on each page of it using the GPU. What I am doing right now is:
G = rand(512,512,100, 'gpuArray');
for i=1:100
G(:,:,i) = fftshift(G(:,:,i));
end
Is there a faster way to apply fftshift without doing it in a loop? For example, fft2 can be applied directly to an 3D array performing the operation on each page separately. However, fftshift does not work like that. Furthermore, fftshift is not supported by pageFun.
Any suggestion?
