Use multiple permalink fields in 1 section
The permalinks plugin itself doesn't support multiple 'permalinks' fields.
I just tested a local install, though, and found I could manually create multiple permalinks for the same record.
Of course, manually creating a permalink isn't really something you want your day to day users having to do.
What we could do is look at creating you a plugin through consulting that automates the creating process for your additional permalinks.
Feel free to contact me via email@example.com to continue that conversation.
Let me know any questions.
