You can customize an existing asset (e.g., Annotation, Behavior) and save it as a preset.
To create a preset, in the Properties panel, customize the color, outline, font, or other elements and then click the plus icon to save it as a preset.
Presets will be denoted by a small avatar icon in the bottom right corner.
You can also save presets as Favorites (See Favorites)
Presets will be added to the right panel (e.g., Annotations) based on their type.
