Can you place a Defining Query (Entity Framework) in external XML?

For example in my Model.edmx file I have:

        <Schema Namespace="dbModel.Store" Alias="Self" Provider="System.Data.SqlClient" ProviderManifestToken="2008" xmlns:store="http://schemas.microsoft.com/ado/2007/12/edm/EntityStoreSchemaGenerator" xmlns="http://schemas.microsoft.com/ado/2009/02/edm/ssdl">
  <EntityContainer Name="dbModelStoreContainer">
    <EntitySet Name="Students" EntityType="dbModel.Store.Students" store:Type="Tables" Schema="dbo" />
    <EntitySet Name="Teachers" EntityType="dbModel.Store.Teachers" store:Type="Tables" Schema="dbo" />
  </EntityContainer>
  <EntityType Name="Students">
    <Key>
      <PropertyRef Name="Id" />
    </Key>
    <Property Name="Id" Type="int" StoreGeneratedPattern="Identity" Nullable="false" />
    <Property Name="Name" Type="nvarchar(max)" Nullable="false" />
    <Property Name="TeacherId" Type="int" Nullable="false" />
  </EntityType>
  <EntityType Name="Teachers">
    <Key>
      <PropertyRef Name="Id" />
    </Key>
    <Property Name="Id" Type="int" StoreGeneratedPattern="Identity" Nullable="false" />
    <Property Name="Name" Type="nvarchar(max)" Nullable="false" />
  </EntityType>
  <Function Name="ListAllStudents" IsComposable="false">
  <CommandText>
    select * from student
    WHERE teacherid = @id;
  </CommandText>
  <Parameter Name="id"
             Mode="In"
             Type="int"/>
</Function>

</Schema>

Is it possible for

<Function Name="ListAllStudents" IsComposable="false">
  <CommandText>
    select * from student
    WHERE teacherid = @id;
  </CommandText>
  <Parameter Name="id"
             Mode="In"
             Type="int"/>
</Function>

to live outside of the Model.edmx and reference it? What I want to do is similar in nature to breaking out the different web.config sections into their own XML file. I don't want to make the EDMX file huge for a project since I will have quite a few defined queries.

**EDIT: Code First is not really a liable options since I will be working with a (legacy) database already defined.
