add existing node to NCM

I may be missing something here, but as a node manager how can I add an existing node to NCM? when you click edit properties, there are numerous tick boxes but not one to add node to NCM?

now i know there is a way through manage NCM nodes, i'm not daft, but that is only available to admin users, not 'node management' security as it should be.

if someone could shed light on this issue asap
