split-horizon with systemd-resolved

I am on an Ubuntu box that uses systemd-resolved to resolve host names.

I would like to configure it, systemd-resolved, to use a DNS server, different than the main ones, just for some particular domain.

Is that possible? I am finding systemd-resolved man page pretty arduous in that regard.

Update: BTW, I know I can do that using a local bind or dnsmasq server, but I would prefer to stick to using just systemd-resolved if possible and not overcomplicate my setup.

Update 2: I have been told on the systemd IRC channel that this can not be done :-(
