School-specific LORs and how to go about them?

<p>Hi, I am an Australian student planning to apply to several US colleges, one of which I will be applying EA. My counselor and teachers have written letters of recommendation which address specific aspects of the EA school.</p>

<p>I would like to know if there is a way to electronically send different letters to the other schools I am applying to regularly, after I have applied to the EA school (ie, would my recommenders be able to change the letter they had uploaded to a more general one after I lodge my application EA? And would this affect anything on the EA school's end?)</p>

<p>If not, I gather that I must send the letters of recommendation and counselor reports to the individual schools via mail. Would I be allowed to get my counselor to apply online for one school, EA, and offline for other schools, regular?</p>

<p>Basically, what is the best way to go about this, where my teachers and counselor have all written letters specific to the EA school, but I want to use the same recommenders for my other schools? Not many people apply overseas, so my teachers are all a bit unsure.</p>

<p>Thanks in advance</p>
