It looks like you'll have to go into the API for this.
I found a couple of methods that you could use to iterate through the exploded steps and retreive the information I assume you're looking for.
Take a look at
GetNumberOfExplodeSteps Method (IConfiguration)
GetExplodeStep Method (IConfiguration)
Those will give you access to an IExplodeStep pointer which exposes the explode step name, components and other parameters.
You can then create a text file to write this information to.
How does one use this?
Well, you'll have to learn some VBA to implement this as a solution. Maybe if you raise the question in the API group, you can get someone to help you with the coding.
