Apply mask from right to left

Is it possible to use a mask that as the user enters additional values, they will appear starting with the right-most digit, pushing older digit entries left as they type? 
For example, I have the following mask: ##.###,##
What I want to input: 100,00
But since the mask starts from left to right if I try to input 100,00 I will end up with 10.000, due to the natural mask comportament.
