alasql use numbering instead of question mark for queries

Question

I am using Alasql to merge json objects.

I have this alasql query:

SELECT Employment.*, 
       EmploymentCore.CompanyCode AS EmploymentCore_CompanyCode,       
       Accumulator_DaysInAdvance.VacationYearValue AS Accumulator_DaysInAdvance_Value,
       Accumulator_AgreementYearlyDays.VacationYearValue AS Accumulator_AgreementYearlyDays_Value,
       Person.UserId AS Person_UserId, 
      FROM ? AS EmploymentCore 
RIGHT JOIN ? AS Employment 
        ON Employment.Id = EmploymentCore.Id 
 LEFT JOIN ? AS Accumulator_DaysInAdvance
        ON Accumulator_DaysInAdvance.WorkNumber = Employment.WorkNumber
       AND Accumulator_DaysInAdvance.AccumulatorId = 'b82'
       AND Accumulator_DaysInAdvance.AccumulatorType = 'd'
 LEFT JOIN ? AS Accumulator_AgreementYearlyDays
        ON Accumulator_AgreementYearlyDays.WorkNumber = Employment.WorkNumber
       AND Accumulator_AgreementYearlyDays.AccumulatorId = 'b59'
       AND Accumulator_AgreementYearlyDays.AccumulatorType = 'n'
      JOIN ? AS Person 
        ON Person.Id = EmploymentCore.PersonId 

And I have these objects:

1. EmploymentCore
2. Employment
3. Accumulator
4. Person

The Accumulator is redundant in the query though. So instead of passing the Accumulator object twice, Is there a way to use numbers instead?

Like:

SELECT Employment.*, 
           EmploymentCore.CompanyCode AS EmploymentCore_CompanyCode,       
           Accumulator_DaysInAdvance.VacationYearValue AS Accumulator_DaysInAdvance_Value,
           Accumulator_AgreementYearlyDays.VacationYearValue AS Accumulator_AgreementYearlyDays_Value,
           Person.UserId AS Person_UserId, 
          FROM $1 AS EmploymentCore 
    RIGHT JOIN $2 AS Employment 
            ON Employment.Id = EmploymentCore.Id 
     LEFT JOIN $3 AS Accumulator_DaysInAdvance
            ON Accumulator_DaysInAdvance.WorkNumber = Employment.WorkNumber
           AND Accumulator_DaysInAdvance.AccumulatorId = 'b82'
           AND Accumulator_DaysInAdvance.AccumulatorType = 'd'
     LEFT JOIN $3 AS Accumulator_AgreementYearlyDays
            ON Accumulator_AgreementYearlyDays.WorkNumber = Employment.WorkNumber
           AND Accumulator_AgreementYearlyDays.AccumulatorId = 'b59'
           AND Accumulator_AgreementYearlyDays.AccumulatorType = 'n'
          JOIN $4 AS Person 
            ON Person.Id = EmploymentCore.PersonId
