Pioneer DDJ SX2 Effects on/off button could flash!

Would you consider allowing the effects on off buttons to flash when an effect is in use. This would be very helpful in notifying the user that an effect is still potent. Take for eg an echo out in Serato DJ. If the Echo out is left on the next track will not be heard until the effect has been killed. This can be disastrous in my experience but if the effects on/off switch flashes whilst the effect is alive then at least it would catch your eye and most certainly jog your memory to avert an oncoming mistake! I do not believe that anyone has implemented this feature yet but I would say that almost every DJ in the world has made the echo out mistake and will continue to do so.
