List of Double Exposure Cameras; 70D?

Ok so I was looking to buy a new DSLR (to upgrade from my 500D) and I really want to know 

which cameras have a built in Double or Multiple exposure option.

I want a feature thats built in the camera, so I don't have to use photo-shop or any other program to

compile them. So not HDR where it takes the 3, I want to take say a silhouette of a person and then say

a texture of something and have the two images get automatically compiled by the camera. 

So a list of As many of the cameras you know that have this feature. 

I would also like to know if the 70D can or can not.

 

Thank you!
