I guess they forgot to make the requisite documentation public. It should be forthcoming, as the documentation team is now aware of it.
Here's what TAC walked me through:
The tech mentioned that there are some limitations or restrictions as to groups of ports that can be configured together, so it may be best to wait for the documentation or open your own TAC case before doing this. Also note that a reload is required each time a port type is changed.
