sorry to bother over here but I would like to ask kindly if someone can let me know if it is possible to buy somewhere second receiver (subRX) board for Orion II and/or internal auto-tuner board please?

I have chance to buy Orion II w/o these options which are mandatory (almost) for me so I am interresting if it is chance to find them somewhere additionaly and install it to it after purchasing the Orion...

Many thanks,
