I hacked it. If you save the compare, you can add this to the file:

  <PropertyElementName>
    <Name>Microsoft.Data.Tools.Schema.Sql.SchemaModel.SqlSchema</Name>
    <Value>ExcludedType</Value>
  </PropertyElementName>

You'll see where when you open it. This setting is not in the UI, but is apparently supported.
