Brandon,
It is possible - in fact I do the same thing.
You can chose the preferred network in input director, choose the hard wired adapter (you can type start > view network connections to see which one is the hard wired one)
If you want to force a specific application to use a specific IP use force bind IP (google it, it's the first link). I use force bind IP to force Google Chrome to use my wifi 4 G hot spot while i relegate my other applications (such as input director) to the local network.
Good luck,
Greg
