Template Question

Hi,

I often find myself doing something like this

[TestFixture]public class XyzTests
{  

  ISomeService _alpha;
  IOtherService _bravo;
  Xyz _underTest;

  [SetUp]
  public void Setup()
  {
    _alpha= Substitute.For<ISomeService>();                // <=== HERE
    _bravo= Substitute.For<IOtherService>();              // <=== and HERE  
    _underTest= new Xyz(_alpha, _bravo);
  }

}

Note the two marked lines. I'm looking for a way to write a template so that I would just type the name of the field - for example _alpha - and the rest of the line is generated.
So I looked into live templates and macros. But I can't figure out how to get to the type of the field (eg, _alpha) so I could fill it in as type parameter to the .For<> clause.

Any idea how to do this would be very much appreciated. This is such a frequent activity for me that anything shaving off a few seconds of it will make my life happier :-)

Thank you & cheers,
Mark
