Obviously, Sending 4 to each school is overkill and unnecessary. But I still don't know which schools I'll be applying for, as I wont get my LSAT score back until the 29th and may be taking them again this upcoming October.
When it comes to adding recommenders like this:

I get confused at what it means when it asks how many LORs that person will write. When I select 1, does it mean for just one school or does it mean the recommender will give me one recommendation that I would use to apply to all different schools?
Underneath it where it asks for the special instructions, I obviously don't want my recommender to give it to all law schools because I have 4, but I don't know what to specifically say in the directions, as I still lack a list of law schools I plan on applying to.
Can someone clear this up for me?
Thanks.
