Question Prevent runtime instantiated timeline from save changes

Hello,

we are trying to use timelines with dynamic bindings to play our game effects, so we instantiate a timeline asset and bind the objects to it at runtime and this works so far. But we got problems when we add tracks and clips dynamically (we dont know the number of targets before hand) to the instantiated timeline, when the game quits, the original template timeline is modified with the added tracks on disk. Is there a way to prevent unity from saving the changes of the asset in runtime?
