Creating a convention to differentiate between HasMany and HasManyToMany collections

[Chris Marisic]

Is it possible to create a convention that says if class is similar to

MyClassA
IList<SomeType> SomeTypesCollection {get;set;}

That would be equivalent to

Override<MyClassA>(a => a.HasManyToMany
(x=>x.SomeTypesCollection).Table
("SomeTypes"))

And a convention that would be like

AnotherClassB
IList<DifferentType> DifferentTypes {get;set;}

That would be equivalent to

Override<AnotherClassB>(a => a.HasManyToMany(x=>x.DifferentTypes))

I'm trying to implement one of the many Convention classes in
FluentNHibernate so I don't have

return AutoMap.AssemblyOf<NotifyRun>()
.Where(t => t.IsA<BusinessEntity>())
.IgnoreBase<BusinessEntity>()
.Conventions.AddFromAssemblyOf<NHibernateSessionManager>
()
.Override<MyClassA>(myClassA =>
myClassA .HasManyToMany
(x => x.SomeTypesCollection).Table("SomeTypes"))
.Override<AnotherClassB >(anotherClassB =>
anotherClassB .HasMany(x => x.DifferentTypes))
.Override<1MyClassA>(1myClassA =>
1myClassA .HasManyToMany(x => x.1SomeTypesCollection).Table
("1SomeTypes"))
.Override<2AnotherClassB >(2anotherClassB =>
2anotherClassB .HasMany(x => x.2DifferentTypes))
.Override<3MyClassA>(3myClassA =>
3myClassA .HasManyToMany(x => x.3SomeTypesCollection).Table
("3SomeTypes"))
.Override<4AnotherClassB >(4anotherClassB =>
4anotherClassB .HasMany(x => x.4DifferentTypes))
)
etc

I find using separate classes for my mapping overrides makes them more manageable. 

See: http://wiki.fluentnhibernate.org/Auto_mapping#Overrides

As for removing the need for the overrides altogether, I'm not quite following. What are the rules for determining which associations are one-to-many and which associations are many-to-many?
