[Koha] 880 field OPAC display

Hello. I have a dilemma which I am hoping someone can help me solve. I want my patrons to be able to see both non-Latin script as well as the romanized transliteration of an item in the OPAC. I have tried linking several fields to the 880 field, but discovered that it will not display all the fields or subfields I choose. For example, the 245 field will link to the 880 field, but will only display subfield a. Also, the 264 field when linked to the 880 field will not display at all. Do I need to do something to the 880 field? Should I be entering the information into the record differently to achieve my goal? Any advice would be appreciated.
