Laravel DB query builder - using multiple 'from' with aliases

I have following query:

SELECT 
    cd_4.userfield, 
    COUNT( DISTINCT (Case When cd_4.disposition_Last =  'ANSWERED' Then cd_4.uniqueid ELSE NULL END) ) AS Answered_Count, 
    COUNT( DISTINCT (Case When cd_4.disposition_Last <> 'ANSWERED' Then cd_4.uniqueid ELSE NULL END) ) AS Not_Answered_Count 
FROM (
    SELECT  
        cd_2.Userfield,
        cd_2.Start_Date,
        cd_2.uniqueid,
        cd_2.Row_Id_Max, 
        cd_3.disposition AS disposition_Last 
    FROM (
        SELECT 
            cd_1.userfield,
            cd_1.Start_Date,
            cd_1.uniqueid,
            MAX(cd_1.Row_Id) AS Row_Id_Max 
        FROM 
            cdrnew As cd_1
        WHERE (
            cd_1.Start_Date BETWEEN '2020-12-01' AND '2020-12-10'
        )
        AND cd_1.userfield = 'Inbound' 
        GROUP BY 
            cd_1.userfield,
            cd_1.Start_Date,
            cd_1.uniqueid
    ) AS cd_2 
    INNER JOIN cdrnew As cd_3
    ON cd_3.Row_Id = cd_2.Row_Id_Max
    WHERE (
        cd_3.Start_Date BETWEEN '2020-12-01' AND '2020-12-10'
    )
    AND cd_3.userfield = 'Inbound'
) AS cd_4 ;

I have 4 Aliases used for above for table cdrnew named cd_1, cd_2, cd_3 and cd_4

I want to achieve the same using laravel query builder:

I tried with following laravel query:

   $sqlquery = DB::table('cdrnew')->select('cdrnew.userfield')
        ->addSelect(DB::raw('COUNT(DISTINCT (
      Case When cdrnew.disposition = "ANSWERED" Then cdrnew.uniqueid ELSE NULL END
    )) as Answered_Count'))
        ->addSelect(DB::raw('COUNT(DISTINCT (
      Case When cdrnew.disposition <> "ANSWERED" Then cdrnew.uniqueid ELSE NULL END
    )) as Not_Answered_Count'))
         ->addSelect(DB::raw('cdrnew.Start_Date, cdrnew.uniqueid, MAX(cdrnew.Row_Id) AS Row_Id_Max'))
         ->whereBetween('cdrnew.Start_Date', ["2020-12-12", "2020-12-15"])
        ->groupBy('userfield','Start_Date','uniqueid')
        ->join('cdrnew AS cd_1',"cdrnew.Row_Id", "=", "cd_1.Row_Id") 
       ->limit(10)->get();

But I am only able to create two aliases. One which is default from DB::Table(cdrnew) and another from join(cd_1). How can we create multiple 'from' statements along with different aliases in laravel ?

E.g:

1. from cdrnew as cd_1 (Aliases 1).
2. from cdrnew as cd_2 (Aliases 2).
3. from cdrnew as cd_3 (Aliases 3).
4. ..... and so on
