Use of 96372 multiple times

Hi: I wanted to make sure I'm doing this correctly...

If I were billing this for the injection of 3 non-mixed, different drugs, I would bill 96372 3x with a modifier -59.

But, would I need to put one charge of 96372 on one line of the bill, and another line with 96372 2x with -59 on another?

Or, as I have been doing, is it OK to do 96372 3x -59 on one line?

Thanks in advance!
