Optional Rec - pair them up with the respective school?

<p>I have many highly distinguished people that know me well... who would be willing to write recs for me... they come from schools such as Stanford, Harvard, Yale... so forth...</p>

<p>My question is... should I pair the person up with the school I apply to... for example one person is a Stanford alumni... should I use his rec only for my STanford app and not say the Yale one, whom I have another person as alumni for... unfortunately i can't use all of them for each app</p>

<p>I would have the alumni write the rec for the appropriate school. And only send 1 additional letter.</p>
