Can we make all Static Mappings use the TFTP URL configured on the parent server page?

[Jeremy11one]

I configured a TFTP url on the services_dhcp.php page for my LAN interface, but when I add Static Mappings for 20 VoIP phones so they'll get reserved IP addresses, those phones don't seem to receive the TFTP url anymore. I have to copy/paste that TFTP url onto every Static Mapping to fix it.

Is there a way to improve this so Static Mappings automatically pick up the TFTP value from the parent page, so changes to the url only have to be made in one place? I suggest adding a checkbox to services_dhcp_edit.php that says "Use the TFTP value from the parent DHCP interface".
