indicate hide component in sub assembly

Hi.

i have an asembly file. consist of another 3 sub assembly. in the main pcb layer, has many components.

main assembly-->main pcb---->pcb, cap, connector...

                      -->cover

                      -->rear cover    

some time i hide one of the components in main pcb assembly.

when i just show every assembly only.

i wonder there  is no indication  that some omponent has been hide in main pcb. until i have to list out  pcb assembly, then i can see a component has been hide.

how to set so i can see a component as been hide in the sub assembly, before i list out the subassembly.
