How to add a custom trigger to an intent

[felixschndr]

(Followup of #3528 (comment))

I'd like to know how to know about expanding the triggers of that intent: For example my SO likes to just say Temperatur (Temperature in English) and expects the current weather. Would it make sense to add such a phrase (or Weather for example or Date for HassGetCurrentDate) to the repo or shall I only add that locally?

@synesthesiam answered

For Temperatur, it might be easier to just add a sentence trigger

However, I think this is not what I want since in when adding a sentence trigger I would have to define the answer myself. As a consequence I would have to duplicate the code of the intent I want to trigger. From my perspective the way to go would be to add a triggering sentence (or word in this case) to the intent as described in Extending built-in intents or to add them to repository directly. Am I missing something here?
