When the user drags-n-drops one topic to another, a dialog appears prompting the user to select the type of relationship. By shift-dragging, the Containment relationship is selected and acted upon.
There are cases in which there could be more than one relationship between two topics (such as an owner of a business who is also a resident in the same place, where Owner/Subsidiary and Residence/Resident are both to be added). When creating this, the longest portion is initiating the process. It would be desirable, IMHO, that once the creation process is initiated, if the user could click on a "+" button to add another relationship (multiple times) it would save time not needing to initiate the process each time.
