Ok verison 1.6.2 is out that allows you to do the following, say we have these 2 classes (that map to the same table)

[UIOMatic("TestWithDate", "icon-users", "icon-user", RenderType = UIOMaticRenderType.List,
    SortColumn = "TheDate", SortOrder = "desc")]
[TableName("TestWithDate")]
public class TestWithDate : IUIOMaticModel
{
    public TestWithDate()
    {

    }


    [UIOMaticIgnoreField]
    [PrimaryKeyColumn(AutoIncrement = true)]
    public int Id { get; set; }

    [UIOMaticField("Firstname", "Enter your firstname")]
    public string FirstName { get; set; }

    [UIOMaticField("Lastname", "Enter your lastname")]
    public string LastName { get; set; }

    [UIOMaticField("TheDate", "Select a date")]
    public DateTime TheDate { get; set; }

    public IEnumerable<Exception> Validate()
    {

        return new List<Exception>();
    }
}

and

[UIOMatic("TestWithDateLimit", "icon-users", "icon-user", RenderType = UIOMaticRenderType.List,
    SortColumn = "TheDate", SortOrder = "desc")]
[TableName("TestWithDate")]
public class TestWithDateLimit : IUIOMaticModel
{
    public TestWithDateLimit()
    {

    }


    [UIOMaticIgnoreField]
    [PrimaryKeyColumn(AutoIncrement = true)]
    public int Id { get; set; }

    [UIOMaticField("Firstname", "Enter your firstname")]
    public string FirstName { get; set; }

    [UIOMaticField("Lastname", "Enter your lastname")]
    public string LastName { get; set; }

    [UIOMaticField("TheDate", "Select a date")]
    public DateTime TheDate { get; set; }

    public IEnumerable<Exception> Validate()
    {

        return new List<Exception>();
    }
}

You can see that both have the same table in the tablename attribute

Now the changes I've made are to the event model so you can do the following

First attach to the event

UIOMatic.Controllers.PetaPocoObjectController.BuildingQuery += PetaPocoObjectController_BuildingQuery1;

then check for the type of object instead of checking for the tablename

    private void PetaPocoObjectController_BuildingQuery1(object sender, UIOMatic.QueryEventArgs e)
    {

        if (e.CurrentType == typeof(TestWithDateLimit))
        {
            e.Query.Where("TheDate >= @0", DateTime.Now.AddDays(-1));

        }
    }

You'll need to be running the latest version in order to get the CurrentType property on the QueryEventArgs

Let me know if you have further questions.
