While designing a Impeller, I'm adding tabs and slots in the assembly where the blades have to be welded to the discs. I've inserted one of 8 blades, added the tabs and slots and created a circular component pattern. The tabs appear on all 8 blades, but the slots only appear on the discs where i've inserted the first / original blade. How do i make them appear with every blade on the disc. 

Thanks.
