We're interested in adding a tool tip for each selection in the content creation drop down. The business purposes is to give more information on what the document / object is and explain what information they will have to provide on the properties
I've found and implemented tool tips for attributes (at a properties screen leve) which are based on the user help for each attribute. This is a bit different though as it's effectively just a D2 dictionary.

A hover text does appear so I kind of get the feeling that it is possible to update. Just not sure how. I'm testing it for the object types user help but given the hover shown above is based on the dictionary value I'm not sure that's the right way to go about it.
Any ideas?
