How do I record in UDF format in Nero Express 6?

When making data DVD (not video DVD, I use DVDXCopy for this function), Nero Express 6 record the DVD in CDFS format in default setup. Is there a way to make a data DVD in UDF format using Nero? My other software B’s Recorder records in UDF format and it seems to be more comparable with other platforms. Nero seems to be more stable when burning the media I am using so if possible I want to use Nero but I really need to record in UDF format. What can I do to solve this problem ?
