Custom dismiss and "move into closed toast spot" animations?

[viveleroi]

I need to provide custom animations for two scenarios and I'm not seeing a clear way of doing it:

• When a user clicks a "dismiss" button, that I've added per the examples on the website documentation
• When a toast closes, the other toasts move up (when reverseOrder is true) to fill that spot - I need to delay this otherwise they move up too quickly and cover the animation of the one sliding out

How should I go about handling these? I already have a custom animation based on the t.visible boolean per the docs but I'm not sure I see any properties that tell me what I need to know.
