Animate text from right to left

I've been trying to animate some text to have the Typewriter effect and I can't figure out how to make the animation start at the right of the text but also start with the first letter of my text. For example my text would say "Learn today", I want the animation to start with "L" and move over to the left to make space for the next letters. Right now I managed to start at the right side but in my example it would make the "y" in "today" appear first. Do I need a specific plugin to do this or can it be done with After Effects options ? Any advice would be appreciated.
