Emacs Ispell to list all spelling errors at once

Question

I am using emacs ispell to look for spelling mistakes. It works well in interactive mode, but I was wondering if I can see all the words with spelling issues highlighted in the buffer itself or highlighted in a separate buffer. I need this because a lot of my writing involves use of technical nouns that aren't in the dictionary and it is a little inefficient to cycle through them, specially since I don't make a lot of mistakes. I am unable to find any clue online and the manual mentions only the interactive mode of usage.
