how can I create a unique patch object

I would like to create a unique object p (patch) so as to preserve some features like faces' color and surface , upon wich i can plot another figures , so as to preserve the previous figures , modifyng only the S.Vertices.
surf=gca;
xlim(surf,[-10 10]);
xlabel('x');
zlim(surf,[-10 10]);
zlabel('z');
ylim(surf,[-10 9]);
ylabel('y');
daspect([1 1 1]);
%first figure
S.Vertices=[1,1,1;4,1,1;4,4,1;1,4,1; 1,1,4;4,1,4;4,4,4;1,4,4];
S.faces=[1,2,3,4;1,2,6,5;3,2,6,7;4,3,7,8;4,1,5,8;5,6,7,8];
p=patch(gca,S);
p.FaceVertexCData=[1 0 0; 0 1 0 ; 0 0 1 ; 0 1 1 ; 1 0 1 ; 1 1 0 ];
p.FaceColor="flat";
%simple object rotation
theta=pi/2;
mry=[ cos(theta) 0 sin(theta) ;
0 1 0 ;
-sin(theta) 0 cos(theta)];
S.Vertices=mry*S.Vertices';
S.Vertices=S.Vertices';
% second figure
p=patch(S);
p.FaceVertexCData=[1 0 0; 0 1 0 ; 0 0 1 ; 0 1 1 ; 1 0 1 ; 1 1 0 ];
p.FaceColor="flat";

copyobj() perhaps?
Make a copy of the patch into the current axes, and modify the vertices in the copy.
thank you very much for your reply but i've found an alternative solution using directly
S.Vertices = [S.Vertices ; newVertices];
