Add "Number of Merged Ideas" Merged

Currently there is a "Merged Ideas" column that can be added to an Ideas report which shows all the names of the idea that have been merged into a parent idea. It would be helpful to have a number that would represent those ideas as well. I don't really need to see the names of all the ideas in the list view. I do, however, need to know which ideas have ideas merged under them so I can click for more details.
