Drag and drop feedback program/package

[Finickynotfussy]

I am a teacher and I'd like to provide students wth customised feedback on coursework by dragging and dropping prepared statements plus some individual ones into a Word doc or similar (so I can print it easily). I have access to a PC or MacBook. Any suggestions of free software I can do this with? I want to create a sheet of comments that's relevant for each student, not to drag comments onto their actual coursework.
