Recommendation from "other"-not a teacher or counselor

Will schools on the common app accept recommendations from a recommender (an employer of mine-an office I worked at this summer) if it is not written on their offline provider form that says “common app” at the top? If I ask my employer to type it on that paper, then I can’t send it to other schools I am applying to that are NOT on the common app/schools that I am applying to w/ different priorities (if you are unfamiliar with it, the top right corner states either regular decision/early action/etc whatever you are applying to that certain school as, since you download a different offline form for each school on your common app)

I was going to just make a word doc answering the same questions that common app wants my employer to fill out before writing the recommendation below. Thoughts?
