If you've uploaded a Report to the Attachment section of an order, you can simply convert that file to be loaded as a Report.
First, you'll go to Inspection -- View Inspections -- click the "i" button to view the order
Then, scroll down to the "Inspection Attachments" area of the order and click on the "Convert Attachment to Report" button.
A dialogue box will come up asking if you're sure you want to perform this action, hit OK.
Now when you scroll down to the bottom of the work order. You will see your original "Attachment" is now loaded in your "Report" area.
This same procedure can be followed to convert Reports to Attachments!
