When creating a new contact list I can't find a way to Auto Increment the sort order. If I leave it blank I see it is -1 in the UI. I can just get all of the existing list SortOrders and add one to the highest value but that ends up a chunk of code and a few API calls for such a simple task. It seems like that would be easy to implement on the API side. Does something like that exist?
At this time we do not auto-increment the sort order value or offer a way to do that. Definitely a feature worth looking at, I'll make sure to pass this on to our engineering team.
