You can create a BAT file and put addnode in there and it will work. I set a path to my datadir because I keep all my blockchains outside Appdata. I also do this because I run more than one wallet of the same coin on the same computer.

Here's mine:
cd %HOMEPATH%\Desktop\TagCoin
start TagCoin-qt -port=7500 -datadir=c:\Users\TroyBlockchains\TagCoin -listen=0 -addnode=tagmining.com
