Vincent,
Sorry currently we don't have any plan to support N-ary association.
We recommend to use multiple binary associations instead of N-ary association.
How about to post this feature on our UserVoice(
https://staruml.uservoice.com)? If it is voted by many users, then we will consider this higher priority.
Thanks,
StarUML
