Dynamic Map on Node Details View

Hello,

If I add a map resource on a Group View I am able to use a variable ( ${Name} ) to display the map that is named the same as the group:

Clik here to view.

However the same map resource on a Nodes View does not have this feature:

Clik here to view.

I'd like to be able to create an interface map of a switch stack, and not show the same map on every Node Details view.  Is this a missing feature?

Thanks
