It is possible to connect nodes in the topology. In the example below the node STKA2 is connect to two previous nodes (SBFQ2 and ISKQ2).

<node id="STKA2" name="STKA2 Stikine R Wrangell">
		<previousNodeId>SBFQ2</previousNodeId>
		<previousNodeId>ISKQ2</previousNodeId>
		<workflowId>STKA2_Forecast</workflowId>
</node>

This for example used when running IFD runs from the forecast panel. 

In the example shows the situation before the forecaster starts a IFD run for the node STKA2. The topology tree shows that

this node has not run yet and that it is connected to two nodes SBFQ2 and ISKQ2.
