Optional (Survey) page at the end of the course

Hello,

I have an optional survey Page (last slide) at the end of the course. Once i fill out the feedback form in the survey page and click submit button, i am able to generate "course-completion" event and course is now marked as completed.

But now i have an updated requirement and want to generate "course-completion" event before the optional survey page (last slide in the course) loads. Could you please let me know if that's possible ?

In Short,
Current Situation -> User reaches the last slide of the course which is survey page and currently it is mandatory to provide feedback. Once user provides the feedback and clicks submit button, course is marked as completed and "course-completion" event is logged.

Proposed Plan -> Before user reaches the last slide of the course which is optional survey page, i need to mark course as completed and "course-completion" event should be logged. User can click Cancel (exit) course instead of clicking the submit button on the optional survey page and course must be in completed state.
