Do you mean so that you can search for it in your saved posts more easily? If so I don’t know of any tools for that yet. I’ve been saving things to Pocket when I want something like that.

Back when I was using Reddit, I set up IFTTT to add my saved posts to a spreedsheet on my google drive. It stopped working a few months ago and I never fixed it. You could try something like that, but it might be easier to just save it with some other service (bookmarks or Pocket type services)
