Hi 

is there away either during or after creating an assembly pattern, to make one of the instances unique such as you can add geometry or manipulate it by adding more bodies or so on without having to alter all the rest 

i.e 

I have a slap, I patterned as below 
 

now I want to manipulate the middle one, hence want to make it unique, i have long winded process of duplicating and replacing the middle one, but figured Dassault must have a feature to make an instance unique, as its readily available in most cad packages,
