I do not believe there is. However, with the pro version you can bulk apply a category to multiple images at one time.
So your working method could be to:
- Bulk upload your images.
- Filter your images using the – Not in a Media Category – filter option
- Select all the images
- bulk edit the images to apply the category.
This video: from the plugin developer will show you how to bulk edit images to apply the media categories. This can be seen at the 3:05 mark in the video.
I did a pretty exhaustive search for the same thing and couldn’t find anything that would apply the category by default. That being said I’m sure you could code a php function for this however that is not my wheel house.
Hope that helps!
