folder.manage syntax and nested folders

I'm unable to get sub-folders / nested folders to work using the vmware_folder.manage state. 

Names are not being parsed and are sent directly to the /vm/{datacenter}/ root folder. There is no parent parameter or way to specify the heirarchy as it's defined. Examining the code, it does not seem that there's either a way to specify an absolute path, or a parent folder.

Thoughts?
