Hello, I am new to RT, and study its usage these days, and I want to add two custom fields, e.g. field1, field2, and make each field1 include a set of field2, how can I do that? I heard of "dictionary" in RT3.5.5 can meet my requirement, but no found it in 3.5.5, where is it? Thank you very much for your hints and advice Yu Suyuan
