Direct Connect Connections and Direct Connect Virtual Interface are now available for you to categorize in perspectives.
Since CloudHealth now shows DC as direct costs, you cannot allocate them the same way you would do as you would with indirect costs using a reallocation rule. One of the reasons we move service items to a direct cost is so users can have more control on how to group these charges within reporting (per account, tag, business unit etc). The best way to break out these individual costs to is create a perspective that groups DC costs separately.
