Physics // different elasticity depending on collision point

Is it possible to set the elasticity of a physics object based on where another object collides with it?

For example with a pinball game, when the ball hits the top of a slingshot, it should have a little elasticity because it's hitting rubber, but when it hits the side of the slingshot there should be more elasticity because it's getting physically repelled.

Is there a way to adapt the elasticity for two different parts of the same object, or does it have to be two different objects, one hidden possibly?

Thanks!

Probably the way to do it would be to use a seperate object for the different parts. The player won't know the difference

Thanks for that; I think you're right — sometimes I think there are more invisible/hidden sprites in my games than visible ones!
