How to merge nodes in graph plot for R2020b?

How should I merge nodes in graph plot for R2020b?
I have the following current source_nodes, target_nodes and distances. However, I am looking to merge some of the nodes depending on distance (like for example, 0.25 and below). I have tried to search online and came across nodejoin but it doesn't seem to work for graph plots with nodes and edges.
source_nodes = [1, 2, 3, 4]
target_nodes = [5, 6, 7, 8]
distances = [0.25, 1.00, 2.00, 0.25]
If possible, I would like to merge Nodes 1 and 5 and Nodes 4 and 8 respectively with new label names made from combining their original node labels like '15' and '48'. I need to keep the connectivity to the other nodes the same.

Hi,
digraph objects represent directed graphs, which have directional edges connecting the nodes. After you create a digraph object, you can try using the object functions to perform queries against the object.
example :-
e = G.Edges
G = addedge(G,2,3)
G = addnode(G,4)
You can follow the below link showing the example of creating a graph with source ,target nodes and edge weights.
You can also modify the label names by giving the names as one of the parameter to digraph function
hope it helps,
thanks.
