Suppose I have 2 rows and 4 columns of subplots in a figure window. How can I add a title for the first row and another title for the second row?
The closest command I could think of is sgtitle, which adds title to subplot grid. I read its help documentation in MATLAB 2020b; however, none of the examples there explains how it is possible to answer my question.

So far there is no builtin function to add more than one title or sgtille to a figure...

I believe you can use text(). I think it will place text on the figure if you tell it to, instead of the current axes. Try it to see.

And, it's not really that complicated, just takes either some trial and error (or more thinking about the geometry and the algebra to generalize than I've got the time/interest to do at the moment to write more general code).
Again from the above starting point just the following
for i=5:6,hAx(i).Position(4)=hAx(i).Position(4)*0.9);end
hTtlAX=text(0.5,0.5*0.96,'New Title Axis Text','HorizontalAlignment','center');
results in
The actual height reduction of 4% off the nominal 50% midpoint of the outside encompassing axes was trial and error. The first line just reduces the height of the two plots above which want to insert the title by 10% of their default height.
Salt to suit...
