Hello. I have to create an Experience Targeting activity that involves applying different modifications to many pages depending on the audience. In all cases, what I have to do is to insert a specific Experience Fragment (imported from AEM) to the HTML element pointed by certain selector. I know I can do it manually, but the pages, audiences and Experience Fragments involved are so many that I'd like to be able to automate the task by using Target APIs. Is this somehow possible? I checked the API docs, but couldn't find anything related to adding modifications.
