You can automatically update the different settings in a project, this means that only the settings that you input are updated, so you don't have to provide the entire project JSON in order to update a single setting.
Atomicity on arrays
Please note that when updating an array-attribute ("reminders", "availability_constraints", "meta"), you will be setting the entire array and not just adding to the existing array!
