Feature request - Clone-stamping across different Texture Sets

Someone mentioned this on the old Substance forums, and the Allegorithmic devs believed it could be in the works for future updates, but I don't believe it has been implemented yet. Since the old forums have been closed, I figured this would be a good place to suggest it again. Here is the link to that post:

To support this, I'd like to add that in a lot of cases, specifically with characters, artists will use two texture sets for their "skin" material. One for the body, and one for the head/face, in order to preserve as much facial detail as possible for high fidelity products/experiences. When painting skin details manually, this will almost always result in some sort of seam across the clavicle/lower chest area, and will be visible if the character happens to be shirtless or wearing low-cut clothing. Clone stamp would help exponentially for cleaning up seams like this. There are many other examples for where this feature would be useful, but I just figured skin seams on characters/creatures would be the most obvious.
