So first, let me make sure I understand what you are trying to do: create a report based on navigation patterns and string/other variable inputs from the user during conversations in Virtual Agent? That's actually a really interesting question.
Doing a bit of digging, the Virtual Agent Dashboard comes up, and notes "administrators can monitor user engagement with the virtual agent to understand topic usage." This is great, but the functionality seems aimed at topic choices, unique users, and monthly users per channel. You've probably read over this, and want something a bit more specific based on navigation and user input, if I understand correctly.
Next, I found Virtual Agent Scripts, which allows you to store user input in variables:

Okay, this seems to be getting closer but is still mainly aimed at topic control and analytics related to topic choices.
Next, I read over the Virtual Agent Plugin docs, which once activated, gives you a wider array of choices with which to manipulate data, but still nothing in the realm of what you want to do. Your question seems like one that should be simple to answer...yet I am not seeing it.
I have no experience doing this, but I guess I don't see any reason why you couldn't store the input as variables via script and use maybe a JSON parser to get and analyze variable results and create lists/reports. The path to getting those values can be ugly, however:

This is a very interesting question, and hopefully it has an easy answer. I hope you find it.
Cheers
