I hope you realize they don't really personalize them for each school. They send basically the same letter to every school you apply so my letter writers didn't care if I had a list of 6 schools or 16. The key is to be organized. I think I'd have annoyed my LOR writers a lot if I'd added schools again and again midway through the process. What they wanted was a list of my schools so one hour they could just look up the email notification request from each school, follow the link and upload the pdf.
The real work, and real question is if they know someone at that school are they willing to pick up the phone for you and suggest you're a really good candidate.
