[7.0.0-rc.1] Zpool with partitions instead of devices

Would editing /boot/config/pools/ be the only way to do this?

Can I use /dev/disk/by-id/ there?

I would like to create a 3-tier system with the NVMEs holding special vdev partitions for the other 2 zpools, and while "zpool import tc" works from CLI, it doesn't get imported automagically, and shares on them aren't overlapped/detected as they are with the cache_ssd zpool created from GUI.

This works (GUI):

  pool: cache_ssd
 state: ONLINE
config:

        NAME        STATE     READ WRITE CKSUM
        cache_ssd   ONLINE       0     0     0
          mirror-0  ONLINE       0     0     0
            sdf1    ONLINE       0     0     0
            sdh1    ONLINE       0     0     0

This not merger'd (CLI):

  pool: tc
 state: ONLINE
config:

        NAME                                      STATE     READ WRITE CKSUM
        tc                                        ONLINE       0     0     0
          raidz1-0                                ONLINE       0     0     0
