You can insert your own title box using annotations, refer the following code
figure;
subplot 211
subplot 212
annotation('textbox',[0.15 0.9 0.1 0.1],'String','Title String','EdgeColor',[105/255 105/255 105/255])
% [0.15 0.9 0.1 0.1] means position the textbox at 0.15 units from figure window left, 0.9 units up from figure window bottom and 0.1x0.1, where 1x1 represnts the whole figure
More information on annotation can be found here. When you go to the properties page of sgtitle, we cannot find the property for verticle alignment, I hope the above workaround helps, if it does not wait for someone from community to answer !
Thank you
