Reward video (continue game)

My game has an Endless mode.

For example: You reach 500 points (in distance) after you die, a game over screen appears.

Is it possible to set a reward video button, to continue the game where you died?
And only visible when your points are between 300-400 for example..

I can't set up a checkpoint because it is an Endless mode, so the scenes are random

 

@Cornerbox See if this helps

 

Then I think it's not possible in an Endless mode. Because the checkpoints will be random.
Thanks for your reply
