SCM ThingTemplate access control

I have 2 user groups which need to access the SCM page for things belonging to different ThingTemplates. User Group A should access only things from ThingTemplates ABC_1, ABC_2 and ABC_3; whereas User Group B should access only things from ThingTemplates XYZ_1 and XYZ_2. And all ThingTemplate inherit a BaseTemplate.
 

How do I manage access levels based on ThingTemplate?
