If I have this hooked up through hdmi and vga at the same time is it possible to have the monitor prefer or auto select vga over the hdmi input if both inputs are receiving a signal?

I currently have this hooked up to my tv and this monitor and use it for an HTPC. It outputs to both tv and monitor at the same time. I also have a second computer that it is hooked up to through VGA. When I want to use the VGA port I don't want to have to go into the menu to switch or turn off the signal from the HTPC.
