Dashboard variables with integrated LEDs

It'd be helpful to have access to dashboard variables in formulas for the integrated LEDs. I've defined several variables at the root dashboard level, and I'd like to use them to control when integrated SimHub LEDs come on, when they blink, etc. For now, I can workaround it by replicating the formulas, but that quickly gets cumbersome when multiple (JS) variables are being used for a single LED formula. It's even worse when it has to be done for multiple aspects of the LED (e.g., very similar formulas using multiple variables for both color and blink).
