Global accent color option in Rise

I'm mostly checking that this doesn't already exist, and I just don't know how to use it, but:

It would be super handy if the color picker available in Rise (for, example, changing text color) had an "accent color" option that was globally tied to the accent color in the course theme settings.

For example, in some blocks I like to use color with some of the type to set it apart or whatever.  Generally I use whatever the accent color is for consistency--but how cool would it be if instead of typing in the actual hex for the accent color, I could just pick "accent color." 

That way, if I later needed to change the accent color, those blocks would update automatically. As it is now (as best I can tell), if I change the accent color late in the game, I'd have to go through each block and manually change all of that type.

IF that does already exist, I'd be grateful to know about it!
