For systems such as return air, there sometimes isn't a direct duct connection from the air terminals to the mechanical equipment with a return air connector. The best example of this is when a plenum is used for return air, and an air handling unit just has a duct which goes down into the plenum to collect the return air.
In reality, each return air terminal is contributing air to an open ended duct. There is no duct connection between the two instances, but there is a flow associated with it.

My suggestion would be the ability to expand on the "Logical" connection between connectors to include flow as well. Specifically, the best way to explain this is as follows:

1. I add all my return air terminals to a system and add an AHU as its equipment.
2. I click the connector of the return air terminal and click "logically connect" or some similar description.
3. I then click the connector on the terminus of the open ended duct.
4. There is now a flow connection from that air terminal to the duct.

Obviously there would need to be the ability to add multiple flow connections to each connector, creating the flow parameter as an additive property.

This would also be very helpful with piping, as trying to model (and subsequently show) every 3/4" pipe connection to fixtures is both time consuming and kind of useless. If we could show a 2" CW pipe to a bathroom, and then logically connect in this way all the flows, it would make piping in Revit a lot more realistic on that scale.
