How do you modify the Requirement page layout

We've added some user fields to the requirements module.

The default display is Required fields, then Alphabetical.

We want to group them in a specific way based on Requirement Type.

I used this code in the Defect module and I think it will work in the Requirements module.

But, I'm not sure how to display it based on Requirement Type. 

Sub SetFieldApp( FieldName, Vis, Req, PNo, VOrder )

  'Sets a field's appearance

  With Bug_Fields(FieldName)

    .IsVisible = Vis

    .IsRequired = Req

    .PageNo = PNo

    .ViewOrder = VOrder

  End With

End Sub

Thanks in Advance for the assistance.
