can I use two tuners for same satellite

Hi

I got 2 x DVB sat tuners In my E2 box
tuner B Is set for bigger dish which Is moveable and tuner A Is set for a stationary dish
I would like to know If there Is a way to configure box set up In a way such I can have 2 tuners for same satellite, for example tuner B (dish with polar mount) Is set with priority to 28.2 E and when dish Is not on 28.2 to get that satellite from tuner A (stationary dish) automatically without setting priority manual
I use OpenAtv 5 Image
