Hmm so this shouldn’t be too hard, but I haven’t really invested any time into it just yet. It is one of the features likely to make it into the next giant update. I would recommend taking a look at the way containers are handled, making your own version of the UI that is used, and go from there 
I have not had a chance to look at it just yet. Currently all integration tutorials are on hold until I finish the building system update due to a lack of time for the project. It is still on the to do list though
