Usage of Column type will create a messed up migration

[ByteCraftServices]

In my migration always the default scale and precision (18,2) is applied to a use defined type. In my case the UDT has does not match 18,2. So the migration cannot be applied to the database, until I remove it manually from the migration.cs file

DBContext.cs:

foreach (var property in _modelBuilder.Model.GetEntityTypes()
                                            .SelectMany(t => t.GetProperties())
                                            .Where(p => p.ClrType == typeof(decimal)))
{
    property.SetColumnType("DefNumeric");
}

Migration.cs:

PerIC = table.Column<decimal>(type: "DefNumeric(18,2)", nullable: false)  //Wrong
PerIC = table.Column<decimal>(type: "DefNumeric", nullable: false)        //Correct

Is there a way to stopp appliying the default scale & precision autmatically to an UDT?
