manually label contours when there are two different contour plots on one graph

Hi I have the following code. I want to be able to manually select which contours to be labeled. At the moment it only selects one of the two contour sets. Is there a way to manual choose which contours are labelled? Also, I would like to add a "£" and "%" sign in front of each label - is that possible?

Thank you !

 figure;
[A,h] = contour(dataA,20)

 hold on 

 [B,t] = contour(dataB,20)

 clabel(A,h,'manual','FontSize',16);

 clabel(B,t,'manual','FontSize',16);

Use the 3-input form of clabel

clabel(CS, H, V)  % label contours in V for handle H

doc clabel % for more details
