Mobile Inventory - Pick Multiple Lots/Replace a Lot for partial qty During Pick Confirmation

Summary: We are implementing Mobile Inventory for Zimvie Inc. and the idea is to accelerate the picking process using mobile devices. Sometimes users doesn't find the complete quantity of a lot on the shelf so they usually pick a different lot for the remaining quantity. While using mobile inventory, they enter the available quantity (less than pick qty) and confirm the pick line that hoping that the remaining quantity will be available to be picked for another lot but actually the line gets backordered and they cannot complete the picking process. This is a show stopper for client.

Please suggest is there any way to overcome this situation? On confirming the below transaction, the remaining qty gets backordered.
