Variable injection when calling a scene

As a user able to create scenes,
I want to be able to pass one or more variables to the « Start the scene » block
So that I can create standard scenes that would only change based on these variables.

For example, there is a scene that sends a Telegram message, and this scene is called by several scenes.
The difference is that you can pass to this variable the user to whom to send the information and the message.

In my case I would like to be able to make a standard scene that would make an HTTP request to Node-RED to send a message to my Sonos.
And I would like to be able to call this scene in several scenes by passing it the room and the message as parameters.
