Changing of normal direction in composite analysis

Currently I am doing on a investigation of composite material on a shell plate 
When assigning the region to the shell on composite layup, the coordinate with normal direction is pointing downwards as shown in the picture 
I would like to have my normal direction pointing the same direction(upward) as my global coordinate 
and have tried to change the CSYS but is not helping 
Where can I change/flip the normal direction on the shell? 

 Thanks
