drloris @SonidZero - thank you.
There are some minor implementation issues with making a set listing. For one thing, I'd need to order it again. For another, I've now done a D4 in this style - which I don't know if people would want included. The real kicker is that doing it doesn't give any cost saving in this process, so it's not something I'm prioritising, without any obvious sign of increased sales.
