Incorrect PO number display in packing slip overview form

Dear all,

I follow the below steps for posting packing slip in AX 2012 for multiple POs:

1. Procurement and Sourcing > Periodic > Purchase orders > Packing slip
2. Selected 2-3 POs and enter delivery date and Delivery note
3. Clicked on "Other" tab, select "Tax Invoice account" and click on Arrange button
4. Post the Packing slip.

In the packing slip form in Journals, in the overview I can see only one PO number is updated whereas in Lines tab, I can see multiple POs. The problem is that though it seems correct, user feels its very confusing by seeing at the overview form assuming that this packing slip has been happened for only one PO.

Can anyone suggest if there is any way to show either <<multiple>> all PO numbers in PO column in Packing slip overview. Can we do this by some configuration or through customization only this is possible.

Thanks,
Pawan
