Is there a way to add a global subtitle over a group of subplots?

Is the a way to add a global subtitle over a group of subplots? I know in the case of a title sgtitle works, but what about subtitle?

figure
subplot(221)
title('First Subplot')
subplot(222)
title('Second Subplot')
subplot(223)
title('Third Subplot')
subplot(224)
title('Fourth Subplot')

sgtitle(sprintf('Main title\n subtitle'))
