[cloudkitty][horizon] change service name list in GUI

Folks, I am trying to configure rating for network data bytes in/out but what I have seen is that the ceilometer uses a different name than what cloudkitty GUI drop down-menu has. Ceilometer using "network.outgoing.bytes" and "network.incoming.bytes" Cloudkitty GUI drop-down list has "network.outgoing.bytes.rate" & "network.incoming.bytes.rate" I have tried to change it in cloudkitty metrics.yml file to match it with the ceilometer but the rating is not calculating until I change that in cloudkitty. Please advise how to change it in cloudkitty.
