So when I use Scriptcards to list all the properties from a Graphic object, nothing on that advanced tab seems to show up yet. The API Objects documentation also does not have any properties for the Advanced tab. I am guessing like most things Roll20 has released lately, that the API was not part of the release. Perhaps someone from Roll20 can come by and confirm this and if they already have this on their roadmap to add. I will add that I would like Roll20 to consider the API quite a bit more considering it's one of their features in their top 2 pricing tiers. API feels like a complete afterthought in all of their recent design choices and that's disappointing.
