Api-key dinamic for OpenAI

Hello everyone,

As there is already an OpenAI node that allows handling the OpenAI Assistant, would it be possible to have one that manages the OpenAI API-KEY, so that it can be created and used dynamically without having to register the credential beforehand?

I know it is possible to use it via HTTP, but to use the native “IA Agent” of N8N, it would be very practical.
