Hosted Elements

[shorty]

Hi guys
I have created a basic electrical layout for a care home. I need to use this for 80 beds. I have tried to create a group but then when I create an instance my equipment isn't hosted. This happens if I copy them as well.
Is it because I am placing them onto the linked model?

Hope, you'll get your answer there.

Thanks
