How to dynamically set virtual distance for Network Node

Hi,

I would like to dynamically set the virtual distance in "Path" tab for a Network Node depending on the flowitems's label value. For example, if one of flowitem has a label named "destination" with a value of 5, I would like to set the virtual distance for the path of my network 5 before it starts travel on the network by a transporter.
I could not find a command to set the virtual distance directly. I think I might need to set virtual distance attribute of network node in a tree, but could not find which variable represents the virtual distance. Closest one I found is "virtualexits", but I don't think it is the right one.
Could anyone can help me how to set the distance dynamically?

Thank you in advance.

The node is called "user dist" and it is buried deep down in the connections/connectionsout attribute of a NetworkNode. Here is a code snipit that you can use to dynamically update the virtual distance of the 2nd path (edge) to a distance of 100 in the OnArrival trigger of a NetworkNode. Notice that it is necessary to re-run Diikstra's Shortest Distance algorithm by calling the optimizenetwork() command as well.

if(toedge == 2)
{
setnodenum(rank(rank(connectionsout(current), toedge),15), 100);
optimizenetwork();
}

Cliff. It is exactly what I am looking for! It works perfectly on my model. Thank you.
