DynamicParameters - Type Mapping like Column Type Mapper with SqlMapper.ITypeMap

Hello,

I do have a legacy Database that have different naming convention to C#. The type mapping for the entity object are easy done with SqlMapper.ITypeMap interface. What is about the filter types? I would like to use an object as filter, but cannot map from C# property names to DB parameter names. Or do I miss some feature in dapper?
thanks

stored proc:

doSomething(param_1, param_2,..)

C#

class DoSomethingFilter{
    int FirstParameter {get;set;}
    string SecondParameter {get;set; }
}

Start by reading SqlMapper.ITypeMap and the parameter-binding path used for object filters, then compare that with the column type-mapping behavior described in the issue. Done should support mapping DoSomethingFilter.FirstParameter and SecondParameter to stored-procedure names such as param_1 and param_2, with coverage for the requested behavior.
