Is it possible to create "SettlingTime" and "Overshoot" datatips on a stepplot via scripts?

I have a stepplot responce. I need to create datatips automatically on "SettlingTime" and "Overshoot" points (see the picture below).
I know how to create datatips on simple x,y plots using the "cursorMode.createDatatip", but it seems like this command can't be used with the stepplot.
Next script allows me to get the characteristic points:
h=figure ('units','normalized','outerposition',[0 0 1 1]);
step_sys=stepplot(sys);
step_sys.showCharacteristic('SettlingTime');
step_sys.showCharacteristic('PeakResponse');
Maybe exist any command to add lables on this plot?

Same problem here. And it seems that there is still no answer. I'm trying to do it in a live editor, but I can't get the data tips.

This is the answer that a came with.
h=stepplot(sys_cl,t);
s_info=stepinfo(sys_cl);
grid
title('Step Response with Text')
h.showCharacteristic('PeakResponse')
h.showCharacteristic('SettlingTime')
h.showCharacteristic('SteadyState')
text(s_info.PeakTime+0.05,h.Responses.Data.Amplitude(end)*0.6,sprintf('PeakTime (s) = %.3f', s_info.PeakTime))
text(s_info.PeakTime+0.05,s_info.Peak,sprintf('Overshoot (%%) = %.3f', s_info.Overshoot))
text(s_info.SettlingTime+0.05,h.Responses.Data.Amplitude(end)*0.4,sprintf('SettlingTime (s) = %.3f', s_info.SettlingTime))
text(h.Responses.Data.Time(end)*0.5,h.Responses.Data.Amplitude(end)*1.05,sprintf('Final Value (s) = %.3f', h.Responses.Data.Amplitude(end)))
