Gateway to Prep Schools Submission

Hello, I was wondering if there was a need for me to submit the whole application on Gateway to Prep Schools. By this I mean I have completed all the required parts of the Gateway application for the schools that I am applying to (Profile, Essays, Fee, Recommendations), and am asking if there is a holistic submit application option somewhere, or if just submitting the individual parts is fine. The checklist is filled out entirely but there is no indicator of the 100% completed like the SAO.

I was wondering this too, although, for me, my application won’t even be completed, as I’m not allowed to get recs from teachers or guidance counselors. Does it matter if Gateway doesn’t regard mine as completed?
