AGS vs Visionaire [scenes]

In AGS there were "before room load" and "after fading in" and "first time room loaded", so all the conditions or particular animations were loaded before and then something happens after fading in.

In Visionaire there is "at the beginning" and "at the end" but where to put all the things like for example adding items to character and some conditions I want to happen only the first time the character enters the room?
