Question on Academic Evaluator Requests

So I’m adding my professors to my common app (transfer student) and since you have to add them individually for every single app I’m wondering if all the evaluations are different. Every time I assign a college to a teacher am I sending an email to them where they’ll have to write a bunch @-) … Or is the app the same and they simply just solve one evaluation and assign it to all my colleges. I provided a link with an image that explains a bit what my question is.

Each recommender uploads their letter to Common App once. Then, you just assign your chosen recommenders for each school’s app, and they won’t get notified. However, they can choose to log into Common App and see a list of schools to which they’ve been assigned.
