generate multiple document in one document

Hi guys, Does anyone know how to generate multiple line items in one document? I have used looping microflow, but it only downloads the last item. I want to download the item that has been selected. Once I select the lot no and click the print button, it should generate a document for the selected lot.  Currently I was able to download only the last selected lot no. Thank you.
