Column Property AutoMapping - fluent-nhibernate

Question

There is o possibility to create a convention for Column naming:
I have this piece of code:
public AutoPersistenceModel Generate()
{
var result = AutoPersistenceModel.MapEntitiesFromAssemblyOf<User>()
.Where(GetAutoMappingFilter)
.WithConvention(GetConventions);
return result;
}
private bool GetAutoMappingFilter(Type t)
{
return
t.GetInterfaces().Any(
x => x.IsGenericType && (x.GetGenericTypeDefinition() == typeof(IEntityWithTypedId<>)));
}
private static void GetConventions(Conventions conventions)
{
conventions.GetPrimaryKeyNameFromType = type => type.Name.ToLower() + "_id";
conventions.FindIdentity = type => type.Name.ToLower() == "id";
conventions.GetTableName = type =>
{
if (!type.Name.Contains("Lookup"))
{
return Inflector.Net.Inflector.Pluralize(type.Name).ToLower();
}
return Inflector.Net.Inflector.Underscore(type.Name)
.Replace("lookup", "lu").ToLower();
};
conventions.IsBaseType = DontMapAsJoinedSubclassTypesInheritedFrom;
conventions.GetForeignKeyNameOfParent = type => Inflector.Net.Inflector.Underscore(type.Name) + "_id";
conventions.GetForeignKeyName = type => Inflector.Net.Inflector.Underscore(type.Name) + "_id";
conventions.OneToManyConvention = m => m.Cascade.All();
}
private static bool DontMapAsJoinedSubclassTypesInheritedFrom(Type arg)
{
var derivesFromEntity = arg == typeof(Entity);
var derivesFromEntityWithTypedId = arg.IsGenericType &&
(arg.GetGenericTypeDefinition() == typeof(EntityWithTypedId<>));
return derivesFromEntity || derivesFromEntityWithTypedId;
}
and an Entity class
public class Organisation : EntityWithTypedId<int>
{
public virtual Organisation Parent { get; set; }
public virtual LookOrganisationType OrganisationType { get; set; }
[DomainSignature]
public virtual string OrganisationName { get; set; }
public virtual string Address1 { get; set; }
public virtual string Address2 { get; set; }
public virtual string City { get; set; }
public virtual string Postcode { get; set; }
public virtual LookupCountry Country { get; set; }
public virtual string TelNo { get; set; }
public virtual string FaxNo { get; set; }
public virtual string Email { get; set; }
public virtual User Contact { get; set; }
public virtual DateTime? DateCreated { get; set; }
public virtual DateTime? DateAmended { get; set; }
public virtual bool Active { get; set; }
}
Finally I want to have a column for, let's say TelNo like tel_no.
So the Convention is if Property contains capital letter in the middle ti should be underscored. Inflector.Net.Inflector.Underscore works fine. But I do not know how to write the convention.
Somethig like:
(conventions.GetPropertyName = type => Inflector.Net.Inflector.Underscore(type.ColumnName))
Thanks
