Fixed Subtitle On-Screen Position

I’m not sure if this the right place to post this or not,but I’m hoping someone can help me with fixed subtitles and moving their position on the screen.

I only used fixed subtitles in my movies for the non-English parts. My problem is that I’m using a 2.35:1 screen, so when zooming the projector to fill the screen, the subtitles are displayed on the panel below the screen.

Is there a way to move them or not since they are fixed and not contained in a .srt file?
