I am excited about the ability to great a group based on email domain “@company.com”. What has me concerned is there is a message that ALL conditions must be met in a group. 

My question: Can I create a group where multiple email domains are accepted? 

Use case:

We have a program for Technology Partners. The partner company has to get approved to participate in the program. Once approved any employee from the company can take the restricted training. My plan is to create a group of approved email domains. Then give the group access to the restricted content. 
My plan is to update the group criteria each time a new partner is approved.
