Feature Request: editable multiselect list

[Kainkainkain]

Hi I really like this CMS concept. I'd like a row halfway between the example tags and multiselect. I want users to be able to multiselect as is, but also the option to add the the global list of choices. I tried the demo and read some of the documentation - now I might be wrong and its already possible or there is a way to do this with the existing setup but I am not sure!
