I often utilize the same template layouts across multiple brands and it would be a huge time-saver to be able to assign swatches from a color theme to the various objects, and have all the respective objects update when a new color theme is selected. So if I have Color 1, Color 2, Color 3, and then select a new color theme, the design could be updated as Color 1 -> Color 4, Color 2 -> Color 5, and so on.
