Probably not, although I'm sure you'd have to pay for it. But they do customize.
Ed is very reasonable, and if you contact him, he is great with communication and will help you a lot. Only thing is, he does not sell heat. That's where the cost comes up a touch. Now if you go with flexwatt, that is cheap. And Rich at Reptile Basics will prewire it for you. For one cage, I doubt you'd pay more than $10-20 for the flexwatt you'd need.
I will go with ConstrictorsNW every time from now on. The cages are really well made and he's great to work with.
