Is there a way anyone knows of to get the nested functionality of categories into a custom field?  I am integrating a "Resolution Category" field into our IT queue on our K1000 and would like to be able to be able to build out nested categories for that field if possible.  The fields for the "Resolution Category" would not necessarily be the same as the ticket category so I don't necessarily just want to modify the category before ticket close, but I also do not want to assault my technicians with a large number of options that could be cleaner if it is possible nest them.
