Two Question Banks, One Result Slide

I have come into an issue, and I was wondering if there is any way to solve this.  My client has a policy that his employees need to read through.  There are two separate categories of employees, so there are two question banks.  The employee will read their policy, then click on the button that reflects them.  This button will take them to the corresponding question bank.  I only have one result slide... as I only need the module to report one score to SCORM.  But, the result slide is trying to combine scores from both question banks when the employee is only taking one.  The employee could score a 100% on their section, but it will show 50% because they didn't do the questions on the other question bank.  Any idea how to fix this issue?  Thank you!
