Hi Debbie -
In Cvent, there are fields called Custom Event Fields that can be created and can be used across different events. You essentially set the question up once and it can be pulled into different events like pulling from a question library.
Here's a couple of articles that explain more about how Custom Event Fields are created and used. Depending on your access, you may have to go to your accounts Cvent System Administrator to get Custom Event Fields created.

Hope this helps!
