In Moodle can we have nested metacourses?

The question is whether a metacourse can have a metacourse underneath it. And at least with a quick test in Moodle 1.7 the answer is no. The course settings question: “Is this a meta course?” does not allow a choice. Instead it says. “No – This course is already part of a meta course.”

What is interesting is that a course CAN belong to two different metacourses. Look at Scenario 2 in this Moodle Metacourses Documentation.
