Could Adobe add a tool for users to create, organize, and use precreated responses to common problems or questions? As a writing instructor, I would find this tool invaluable, as I respond to common problems in student writing. I expect other professionals who encounter situation where they offer similar responses to multiple documents would benefit from this tool. Thank you for considering this request.

Brent, I suggest using MS Word or Notepad to create a document for such canned responses. You can open up the Word/Notepad file, locate the desired response, copy the text, and paste the text where needed in the Acrobat file. If you keep the Word/Notepad file open - but its window is minimized or underlies other windows - its toolbar icon will be easily accessed.
Remember, a Notepad file is plain text. It will not have Word's formatting for special characters that may or may not be replicated in Acrobat.
