Scripting: any way to catch the save event?

Hi there.
Is there any way to catch the save event, and possibly abort it ?
I was hoping to leverage something similar to TB_sceneOpened.js for opening, but apparently I cannot find such an event for saving. The final goal is to prevent the artist from saving into a given location.
Thanks. Stefano

I have a same issue with that. still not solve. Anyone Help.
