Not able to select multiple batches in packing list (bundle item)


I sold 100 units of a bundle, but for its child item I have 2 separate batches available (batch 1: 60 pcs and batch 2: 40 pcs).

In the packing list table, it does not allow me to add multiple batches…I can only select one batch. Does anyone know how to fix this?

Does any one know a workaround for this?
