is there a way to mark all images uploaded as unannotated all at once?
We do have the option to manually label images as “Null” or delete annotation batches. Deleted batches do retain annotations, however (unless they are completely deleted from the project).
We have received this feature request recently from a few others (to mark all images as Null - for context to others that see this post: this is what we discovered was the true need on our in-app chat conversation).
I just relayed your request to our Product team as well.
