I just started playing around with the new forms designer and noticed that I can't set a default value for a people picker control (e.g. current user). There's one for text controls, but not for the people picker. In this video https://www.youtube.com/watch?v=ZTm07OFxhpE you can see three options in the rules tab - on form load, input and submit. Load is obviously what I woud need here, but it's not visible for me. I can only create rules for input and submit.
