No, I do not think that feature exists, but you can just use any existing webhook with the newly created channel or use the Event API to get the same result.
Incoming Webhooks
You can redirect an incoming webhook to any channel by providing the channel name as parameter in your call. (see Channel override)
Outgoing Webhooks
Your existing outgoing webhook will work with any channel, as long as you use triger words when you created them. If that is not an option, I would recommend to look at the new Event API that would allow you to get the same functionality as with outgoing webhooks, but without having to provide a channel name in the first place. Check out the event types message.channels and message.groups.
