Status - DHCP leases: add description w/o static mapping?

[Cabledude]

Hey all,
pfSense is working well for me, I'm currently doing some cosmetics. So in the DHCP leases table, I see clients with
IP/MAC address, hostname, description.

The "description" field is empty for all clients that receive an IP address dynamically from the DHCP server. I'd like to change that, but I can't find how.

I do know how to make static mappings - and then I can actually fill the the description field, but static is not what I want for most of the clients.

Actually I don't think it's possible, this is what I read in the Netgate Docs:

*"Leases

The currently assigned DHCP leases are viewable at Status > DHCP leases. This page shows various aspects of the client leases. These include:

The assigned IP address
The client MAC address
The hostname (if any) that the client sent as part of the DHCP request
The description for a host with a DHCP static mapping
..."*

This implies the description field is only there for static mappings.

Just thought I'd ask anyway.

Thanks!
Pete
