If you want to limit the return values from any of the resources on a group details page then a macro contaiing the containerID or contanerName is needed.
This enhancement would boost the functionality of groups enormously, for example right now I can use account limitations to restrict what is viewable, but I have to have a user-account that is subject to those limitations to see what they are. With this the NOC staff could see the same view as the customer looking at their portal.
Jan Pelousek mentioned there was an item for this already, so let's generate some community interest for this.
