I have a huge png file folder (1000+ png files), and I want to use them as 2D and UI Sprite. But when I import these, it's imported as Default. I can change each of these manually, but since there are a number of files, it would be q really tedious and time-consuming task. Is there a way to change these file's import setting via script, or just import as 2D and UI sprite setting, not Default?
