Pihole V6 - Adding Multiple Static IPs IPv4

Hi,
I have used my router (Edgerouter ER4) for DHCP, but as I have one Pihole V6 on Eth0 (for wired LAN) and a second Pihole V6 on Eth2 (for Wi-Fi), now I want to use the DHCP from the second Pihole, where some 20 devices all have a static address. Is there an easy way to move from dynamic IP allocation to static IP allocation?
It looks like one have to enter for each device MAC,IP,Name, which can take time as there apparently isn't an way to click on a dynamic allocation to change it to static.
Thanks - Steen

You can edit the appropriate section of the pihole.toml file.

Thanks
