EWM WT immediate confirmation and LOSC

Hi, I have putaway process from production with multiple LOSC steps A->B->C->D. Everything is working as it should. The problem comes when I want the first step to be confirmed automatically. When I set the warehouse process to confirm from A to B wt immediately, LOSC does not work. I understand this because the LOSC logic is called when the wt is confirmed and in this case the wt is created as confirmed. I can run a job to confirm wt in the background but I'm looking for a more elegant solution. Any idea is welcome..
