Recommenders

Hello,

I have an additional recommender on Common App. I was wondering if they would have resubmit a letter for each college. I ask since I am not sure if my recommender tailored their letter for a specific college that I have applied to earlier (UPenn). If so, what do you recommend me to do? Should I erase the recommender and then add their information again?

Bump! I have the same question too.
