It seems like the only way to create a Top Container profile is during the time that one is creating/browsing for a Top Container to link to a collection. This seems very unintuitive since Top Container Profiles have a much broader use. It would make sense to me to have a create option under Profiles for "Manage Top Containers"
Currently, it's only possible to Browse.
It would also make sense to have a Create Container Profile under the "Create" menu.
