A recent change was made to invoicing to make it like the quoting feature where you select everything step by step in a left pane and it populates in the right pane...

The problem is this then limits the ability to edit invoices on that right pane.

For example, it limits you if a user wanted to add a PO number (which is necessary on every single invoice or any additional tertiary details under a line item perhaps)

So that is now unfixable unless a person downloads the invoice document and has a PDF editor to manually edit the document (same with adding a PO number)
