Batch Number Programmed for Sales and Purchase

Yes the Batch number functionality has been programmed  for FA. It works fine for the sales and Purchase modules. But in Manufacturing I have a problem to implement.

From workorder the Advanced Manufacture will work fine, because I can bring the batch number on the Issuing Stock page. But for Assembly and Unassemble I could not get any idea to program the batch number without adding an intermediate form.  If I add an intermediate form, it will be look like the Advanced Manufacturing.

So I am looking for Real time users feed back to program the manufacturing section.
