Floor Change Connector

Hi,

I am currently in the process of building a CWS pipe sizing model. I completed the top floor and copied the rest of the floors (6 Storey Build). After copying each floor as they are exactly the same I have added a floor change connector in order to connect the pipes within the riser as it would in an install. The Schematic shows the pipes connected in the isometric model. However, when I add a system marker in order to size the pipes on each floor it only sizes them on the current floor I am on rather than the system as a whole? Would it be preferable for me to draw each floor system in rather than copy or is there a way around this?..

Thanks,

Josh
