Separate "on touch down" and "on touch UP" events for when the user taps an item in a scene!

Currently, there are "tap" and "long tap" options.  But it's impossible to trigger any tasks until the user's finger has released the button.

I have some specific ideas that require actions to happen immediately when a button in the scene is touched, not just when it's released.  I'd also like to be able to check whether the button/image/item is still being pressed, and trigger an "exit action" when the button is released (the current "tap" feature is basically an exit action for a button, so that's already there; just not an "enter action" for buttons)

I understand that it'd be impossible to trigger a long tap without also triggering a button's actions assigned to its "entry," but if you don't want to use its "on entry" you could just leave it blank there.

Please!
