How to save group arc levels to a scene in plan view?

Arc levels of a group (or multiple groups) can be configured in plan view and saved to a scene. In edit mode, select one or more groups in plan view and click on Presets to open a new panel. This is where you can adjust the arc levels of each selected group to be at your desired levels before you save it to a scene.

Once you are happy with the levels you have selected, click Save arc to scene. This will open a new dialog which allows you to select a scene number to apply the arc levels to. This will attempt to apply the arc levels across all groups to that same scene number. This will overwrite any values that are currently set.
