DHCPv6 /56 Prefix Deligation

I have a TZ-670 currently running SonicOS 7.1.1-7040-R5387. With the 6.x version of SonicOS you were able to set a preferred prefix delegation with a prefix length. My ISP provides both a /64 and /56 prefix but without this hint with the prefix length in the preferred prefix delegation I only get the /64.

Since it is best practice to not subdivide a IPv6 /64 and I have IPv6 on multiple interfaces in different zones I would really like to get back to getting the /56 prefix.

Also along the same lines when I was able to get a /56 prefix delegation there was no easy way to assign addresses from this on more than one interface without having to include the entire /64 subnet address from the /56 delegation.

(Yes this is a reposting of a question I had from almost 2 years ago and still no one sooms to have an idea on if this is possible)
