Mapping a cascade dataobject that relies on multiple tables

Hello,
I'm currently porting the DAL layer written with EF6 to Dapper, and I'm facing some issue...before writing here I also posted on StackOverflow but with no luck.

I'm in the scenario that I've got an object, let's say TableA, that has some related object on TableB that turn on TableC

I've tried to use the overload of Query but it I'm not able to perform the second split

var sql = @"SELECT  *
        FROM   TABLE_A A
        INNER JOIN TABLE_B B on A.IdField = b.IdField WHERE SOME_CONDITION"

                var res = connection.Query<TABLE_A, TABLE_B, TABLE_A>(
                    sql, (item1, item2) =>
                    {
                        item1.TABLE_B = item2;

                        return item1;
                    },splitOn ="IdField")

                    [Omiss]

Is it possible? How?Thanks

The issue names Dapper's Query overload, splitOn, and a TABLE_A/TABLE_B/TABLE_C mapping scenario; start by tracing the multi-type Query entry point and splitOn behavior. Confirm whether nested multi-table mapping is supported and define what a complete answer or missing capability would need to demonstrate.
