Notification target selector

[BadFlo]

Hello,
I'm using this nice integration for a few months now, before the UI-controlled configuration.

Since then, I wonder : Would it be possible to add a target selector in the action ?

Targets
List of channel aliases defined in configuration.yaml.

As stated, you should only use targets that exist in the configuration, so it may be not so hard to have a drop-down selector menu in place of the "easy to fork" freetext box ?
