Wilk1, you're out of luck, at least for now. I spent a lot of time trying to get the new discretes to work with my Evu 5100, and it simply doesn't work yet. If the 5100 doesn't have it, it's unlikely the 3100 has it and virtually impossible that the older 4700 will have it.

I'd suggest doing what I did - sending an email to Evu and asking for this to be added to the software. If enough people ask for it, they may make it a higher priority item.
