Taking January Subject Test

So due to many reasons I have not been able to take the SAT subject tests until this January, and I realize that is a problem when applying to ivy colleges. I checked online and both Brown and Columbia accept subject tests from January. So my question is when I send my application without the subject test will I be put in with the rolling applications until my test results show up? Is there a way to let them know that I will be submitting my January SAT subject scores?
