Currently many routers (I’ve tested and written a tutorial on Ubiquiti, and OpenWRT) allow you to set the subnet you want. In addition to that, some ISPs have pages that have details on how to do this in FreeBSD, OpenBSD, Gentoo, Windows, Cisco, etc. Of course, the modem / router / switch / access point provided by the ISPs may not allow you this, but it’s certainly possible.
If anyone’s interested in my tutorial for UBNT devices, you can view it here:

Although I do get a /48 from my ISP there is nothing I can manage about the subnetting. The 16 bits between my prefix and my networks are assigned by my router using DHCPv6-PD and there is nothing I can do to set these bits. They are assigned to my networks sequentially.
I don't think it is feasible to use those bits with a special meaning.
