DHCPv6 remote-id TLV 37 (like option82)

We are implementing ipv6 on our network, which includes DOCSIS as well as pmp450.

In DOCSIS DHCv4, we use option82 to assign cpe's to the modem the are bridged through.

In Cambium pmp450, we are doing the same thing with the AP's tagging of option82 setting.

With DHCPv6, is there a way to tag the solicit message with the remote-id of the sm it's bridged through, similiar to how option82 works in dhcpv4? Looking at our DOCSIS devices, this appears to be TLV 37.

Another option would be to have a dhcpv6 relay option in the AP, and just include tlv 37 in the relay
