One dish two receivers

[wiseguy4u]

Is there a way to connect two receivers to one dish without using twin output LNB and receiver LNB out. I am talking about reverse of the diseqc switch.

I use an AB Switch, input from the lnb, output to 2 receivers, but it is manual.

Or use an SPS (Smart Priority Switch) to do the job automatically.
