The ability to copy and paste across multiple modules is an element that is highly desired and missing from Sage.

Eg, created an SO with over 100 products. now I have to type all 100 products again in a PO.

This means that a simple task becomes quite lengthy and drawn out.

The feature would just allow you to copy and paste all information and put it in the PO, whilst still allowing the user to modify things like price and qty.
