Chamber Box with single inlet, multiple outlets or multiple inlets, single outlet

[oovali]

Hey everyone!

I've been trying to create a chamber box family where i want one inlet, multiple outlets or the opposite with single outlet multiple inlets. Below i shared an image where i tried to show the example by using ducts. I want these chamber boxes to carry out air flow values so that i can see the total flow rates at the entrance of the AHUs.

(For example; Inlets: A,B,C -->Outlet:D i want D to show A+B+C total air flow rate m3/h.)
