Chain Relationship from CSV

I am trying to display a chained relationship from a CSV file that has a procedure in Column 1 and its called procedures in Column 2.
Example
ProcedureName,CalledProcedureName
A,B
B,C
C,D

I am able to create the relationships and display A->B & B->C & C->D but I want to to be able to display the chained relationship such that we see A->B->C->D as one long chain. Any help would be appreciated, thank you!

Are you using ‘Create’ or ‘Merge’ to an the nodes and relationships? Can you share your script?
