Need Plugin or Feature Request

Is there a plugin or can I please request a feature to be able to label Groups and/or Objects with a color label. It would be very good to be able to group similar Groups together and to even be able to search based on the group color. Photoshop has something like this.

My workflow is that I am making desktop interfaces to give to the developer. He likes to keep all the Animated parts of the UI separate from the Background Parts, so using symbols don’t really work for us as the Dev would have to manuallly break apart the animated with backgrounds.

So color groupings would help so much
