How do I detect a touch release that's outside of my actor?

Like in my controls I have
If
-Touch Pressed
do
-Set a boolean to true
Else
-If
--Touch Released
-do
--Set a boolean to false
This is all fine except for when the I touch my actor and then drag my finger/mouse outside of the actor and release it there...then I don't know how to detect that in order to make it act like as if it was released while still on my actor.
My current solution right now is to make the actor (a control joystick) large enough and hope the user doesn't drag outside of that large area
