Can't Use Shake Reduction on Portrait Mode Video

Hi, all,

I am new to video editing. I want to apply Shake Reduction to a video I made with my Galaxy S9+ in portrait mode (1920vx1080hx24b). i get the error message, "Shake reduction requires clip dimensions to match project settings. Create a new project." However, all of the available presets are in landscape mode (1080vx1920h). Many thanks for whatever yall can come up with.
