Syncing with Scrivener - Deleting events

I synchronized my project in the Scrinvener with Aeon. It happened that I deleted 21 scenes from my project in the Scrinvener. Aeon removed those scenes from the Narrative, but left them in the Timeline. I didn’t need those scenes neither in the Narrative nor in the Timeline…
It would be great if I had the option to choose whether to leave deleted scenes in the Timeline or not. I was lucky that I deleted only 21 scenes, but what if I had to delete 50 or 100 or 1000?
