Colleges generallly get electronic transmissions of score reports. An SAT report contains info different from a subject test report so technically there is some kind of division although it is still part of the same transmission. You are likely misreading what colleges require and you cannot split hairs via interpretation of score choice in relation to the content of the electronic filing.
The real issue you need to determine is what does the college actually require regardless of the format of the transmission. Contrary to what many beleive, there are actually only a small number of colleges that require all scores and what they actually require varies. Go here and review this thread (through to the end so you get additions and updates) to learn of colleges that actually have an all scores rule and what it means for the particular college: http://talk.collegeconfidential.com/sat-act-tests-test-preparation/1912440-must-you-submit-all-sat-act-or-sat-subject-test-scores-p1.html
