I think I may be getting a sense of what you have going on here. So in your "left" image, it shows the 802.1x "Access Policy". The only settings that tie to that policy are in Switch>Access Policies and they look like this:
Group Policies, on the other hand, are configured under Network Wide>Group Policies. They look more like this:
I believe there are two ways you can assign the Group Policy to a device. One is manual as you observed and that would be annoying. The second is to go to Security Appliance>Active Directory and link your Active Directory Group to the Meraki Group Policy. I don't believe this shows up in the dashboard when you view a computer but it definitely works. Then you can just assign users to that Active Directory Group and they'll automatically get the permissions from the Meraki Group Policy.
