Is there any Pvt API to update transaction temp id in wsh delievery details table

Hello

We want to scan serial number for serial controlled item at sales order issue after pick confirm but before ship confirm using MSCA.

seeded MSCA allows us to enter serial number at ship confirm only but we want to scan serial number after pick confirm.(just like we do using oracle shipping form)

Thats why we want to use custom MSCA page to populate serial number.

Please let me know if you know any pvt API which can populate transaction temp id in WDD so that serial numbers can be captured.

Thanks & Regards
