In theory, yes. In practice, we encounter this [issue](https://gitlab.kitware.com/paraview/paraview/-/issues/19990) with the current implementation. There will be some fine-tuning needed to enable updating extract generators from a Live session in the GUI. We can do that in a following iteration. I don’t think it’s going to be complicated.
