Ability to take arbitrary strings in order to support dynamic templating or custom post processing. For example, HandleBars Tokens like {{myColor}} or a css variable like var(--brandColor)
The use case is injecting some "merge" tag like values that impact companies with multiple brands associated.
Another option would be the ability to custom extend the Color control. Based on the docs/current samples for the v2 plugin API I am not seeing a clear way to do this.
