Save Multiple Aspect Ratios in one project

I would love to save a 16:9 and 9:16 version in one project . When I edit for 16:9 and then want to export to vertical (9:16) I have to go in and re-scale the screen recording to fill the screen. This messes up the 16:9 version. Saving the zoom/scale and position for each aspect ratio would be amazing.
