Resource - What Group has Access?

Resource - What Group has Access?

We have groups and users are part of groups. When I get asked who has access to a resource, I cannot just click on a resource and know this information. 

1. If I click the resource, it does not show what group the resource is associated with.  
2. If I click Resource Actions >  Share with Users/User Groups, it doesn't show that the resource is shared with any group. (Because its not shared)

The only way I know what group the resource is associated with is by going to Groups > click the Associate Resources, then search all resources with the resource name to see if the resource is part of the group. I have to check each group this way to see where the resource is associated. 

Is there a better way to check what Group a resource is associated to?
