How do I make a tween stop and then carry on after a certain amount of seconds?

local object = script.Parent

object.AnchorPoint = Vector2.new(0.5, 0.5)
object.Position = UDim2.new(0.406, -100,-0.5, 0)

wait(15)
object:TweenPosition(UDim2.new(0.406, -100,0.8, 0), Enum.EasingDirection.InOut, Enum.EasingStyle.Linear, 10)

So this just makes it go from top to bottom, but I want it to come from top then stop in the middle for a certain amount of time and then carry on to the bottom, how do I manage to do this?

All feedback is very much appreciated.
