How to set a default image path when inserting from desktop

When you click on the image icon the Prezi App open a window.
How to set a default path for the image you want to pick up?

Thank you for helping

@johnny_zschau Even though it is not possible to set a default path, once you insert an image, the next time you would like to add another one the folder you previously used will be opened so if you have a dedicated folder for image files to be used in presentations, you do not have to search for it each time.
