It depends on which printer and which slicer you use. With Simplify3D, or with and UMO+Cura you can just put the correct nozzle (T0/T1) in the startup gcode, with an UM2, using UltiGcode its different, but also very easy, you just need to make a manual change in the first gcode lines.
You can all find it here;

Hi Bob... I cannot help much but yes there is a Plugin that will do this for you. It was mentioned on one of the forum threads several weeks ago when someone asked the same question as yourself, but I cannot remember its name. Hopefully someone will post it for you, if not try posting under the Cura/Marlin sub section, or try and find the thread.
