Develop an option to choose different Lumio slide sizes (ex. Doc size (8.5x11) or Presentation (16:8), so that when we upload a specific size PPT or Canva presentation it stays the same size and we don't have to spend a tremendous amount of time resizing and reformatting everything, and so that when we upload PDFs or google docs we can select the size we need (and even have the option to have a lumio presentation use multiple sizes in the same presentation (ex. use both 16:8 and 8.5x11).
