Universal rule that applies to all intents?

Is there a way of a rule to be applied to all intents without having to provide the name of each intent separately? I see there is a similar question here, so I was wondering if there is a keyword such as “any” in RASA 3, so that the rule applies to all intents.

What I want to achieve is for RASA server to always communicate with an external service or API, and I will implement this using custom actions. But I want this action to always be executed whenever an intent is triggered.

Any ideas?

Thank you in advance.
