ETO : How can I add labor cost rather than B1 to the ETO work orders and charging it to different Jo

I setup the ETO so that any B1 amount is charged to certain Job cost account . The process is as follows :

1- Build the BOM and Routes for more than 20 parent items which consists the project WBS

    *Routes includes one Cost Type only (B1) ,the amounts/hours are entered by the Manufacturing Route Program

    * BOM includes one Cost type only (A1)

2- Build the ETO Project WBS

3- Run Order processing program

4-Create project quote and accept it

5-After accepting the quote , I did the AAI setup so that :

*The Material amount (A1) of each phase/Parent item of ETO WBS is loaded to the corresponding account in the Job Cost
