Order of delivery schedule line counter at schedule agreements from MRP run

Currently we are using schedule agreements for our long term external suppliers, but we are facing a problem with the order of new delivery schedule lines created during MRP run.

Because of master data settings like, lot size, rounding value, plan delivery time and planning time fence to set as firm new requirements, multiple schedule lines are created with no order for schedule line counter.

Does anyone is aware of a BADI, user exit or customizing control to have this schedule line counter in order?

Thank you
