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.

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,
