Hi,
I didn't able to understand your actual requirement because EA26 itself is capable for parallel processing, If you want to play with contarct account selected for a job please check if you can put you custom logic in below FM.
Object FM
AR_ACCT_MX | ISU_DYN_MASTERVK_INTERVALS |
AR_GPART | ISU_DYN_GPART_INTERVALS |
