Yes, please read what Dark has linked, it was written for this very reason.
Also your target line is a little wrong, its missing semi-colons it should look like this.
And so on, note that then name of the folder inside your directory will take the place of @mods etc so for example. If I have lets say Isla Duala, An SMG Pack and some units it would go.
"C:\Program Files\Bohemia Interactive\ArmA 2\arma2OA.exe" -nosplash -mod=@Duala;@SMG;@BBUnits
