So, there’s an extension under Visualize Path->Number Nodes… that will take any path and convert the nodes to numbered dots. You can change the text and dot size.
With an appropriately simple path (Path->simplify might help you here), you can quickly go from the path on the left to the CTD on the right:

The dots and numbers are grouped together, you’ll need to break them apart to manipulate any individual number or dot placement. I’m sure someone will find a fun use for this!
