Print the variable value from the different sessions

Hi friends,

I have some requirements from client that they need to print the variable value of all the sessions as pdf. 

Example: 

If the learner visited the course and attempted the questions, which stored in xyz variable.

when they again visited and this time they have chosen to restart the course and attempted the question again. so it's the 2nd session value.

Now, client wants to print the xyz variable value of both sessions.

is there any possibilities that it can be done in storyline, by using javascripts or any other methods?

Please share the solution, if anyone have  achieved this.

 

Thanks in advance.
