On a plain (headless) Raspbian system, what I did was to edit
/etc/dhcpcd.conf and added the following two lines at the end:
interface eth0
static ip6_address=2001:<more of it>:4001/64
That causes dhcpcd to allocate that one in addition to the one it
calculates from the MAC address.

Thanks for the suggestion, which I will try, but I have had problems with even
dhcpcd.conf on a raspberrypi. Systemd instructions go into great detail, but
it still does not enable more than one IPv6 address per interface.
The stanza which I quoted above does exactly that:
