Import Storyline 2 quiz bank questions into separate Storyline 2 project

Help!  A coworker and I have been building separate parts of a course and have merged our scenes/slides using the import feature.  I set up the quiz bank in my file and we imported my slides/scenes into her storyline file.  However, the slides to "draw from bank" didn't bring over the quiz banks.

How do we import the quiz banks from the one file to another?  Thank you in advance for any help anyone can provide.
