Yes, you can use one of Channel editors for D series. Export channel list, modify it and import back to TV.
But notice, support for D series is quite new, so apps are still in test phase. I mean, you can brick TV.
Here was a channel editor topic, you could post there and attach the channel list you have.
One of versions is available from here, other you can find on wiki.
