Send for Signature - Can't add file from template library

Since the recent update a couple days ago the send for signature page has got rid of the page to add documents from the library. This is a huge problem as we have to open adobe acrobat use the fill and sign, then open the web base platform upload the document, add the library doc and send. We used to be able to fill out and sign the contract send for signature add our payment form all from Adobe Reader. Why the change and is there a setting to get this back?
