Hello. I am trying to see if I can update an ontology of an already annotated data set so that I can add new classes. Previously i had already created a new project, and created some tasks to annotate 3 seperate data sets with the same ontology of classes. After annotations were finished, I wanted to go back and add a few more classes so that we can go through the images again but keep the already accepted classes that were previously annotated. Is there to do this and then create another task on the project so that annotaters can review the images again, see the previous annotations, and have the ability to update the image with new annotations from the new classes? This would also be relevant when importing a data set that has already been annotated with its labels, and you want to modify those classes but keep old annotations as well. Thank you and looking forward to your response.
