Implementing "nested" properties in Entity Framework

Question

Edit: looks like this is called a "complex type" in Entity Framework, and I see how I would be able to set the name on columns for having once complex type contained in a class, but I don't know how/if you can do it with multiple of the same complex type contained in the class.

EntityFramework 4.1 Code First incorrectly names complex type column names

Since Castle ActiveRecord has been sunset, I am moving over to Entity Framework 5, however I don't know how to accomplish the "nested property" concept that Activerecord had:

http://docs.castleproject.org/Active%20Record.Mappings.ashx#Nested_5

http://docs.castleproject.org/Default.aspx?Page=Nested%20data%20%28NHibernate%20components%29&NS=Active%20Record&AspxAutoDetectCookieSupport=1

I've done my googling, but I'm not sure that "nested" is the proper terminology for this concept in EF, if it even exists. Here are my tables and classes that I had in Castle ActiveRecord, can someone please provide the EF terminology for this and how it can be accomplished:

The Address property on AmaStatementEntity marked with <Nested(ColumnPrefix:="FL")))> maps to the database columns FLStreet, FLSuite, FLCity, etc.

Once I found the correct terminology I was able to find the answer:

Entity Framework - Reuse Complex Type

for my specific scenario this is how you would do it (example shows mapping of one of the comlex type references):

        modelBuilder.ComplexType<AddressEntity>();
        modelBuilder.Entity<AmaStatementEntity>().ToTable("vAMA");
        modelBuilder.Entity<AmaStatementEntity>().HasKey(a => a.AMAId);
        modelBuilder.Entity<AmaStatementEntity>().Property(a => a.FacilityLocation.Street).HasColumnName("FLStreet");
        modelBuilder.Entity<AmaStatementEntity>().Property(a => a.FacilityLocation.Suite).HasColumnName("FLSuite");
        modelBuilder.Entity<AmaStatementEntity>().Property(a => a.FacilityLocation.City).HasColumnName("FLCity");
        modelBuilder.Entity<AmaStatementEntity>().Property(a => a.FacilityLocation.ZipCode).HasColumnName("FLZipCode");
        modelBuilder.Entity<AmaStatementEntity>().Property(a => a.FacilityLocation.Country).HasColumnName("FLCountry");
        modelBuilder.Entity<AmaStatementEntity>().Property(a => a.FacilityLocation.State).HasColumnName("FLState");
