Amending a Report

I just had a game with your typical a-hole, sore loser. So I do my civic duty and toss him an "Unsportsmanlike Conduct" and go to reviewing the damage report. He proceeds to pop off. Admittedly, I had a rough game; low kills, low damage, etc., but here were a few of his gems:

• are u autistic?
• ur embarassing lucian; go to doctor and get brain checked out; good for ur health
• at this point, i think going to doctor for anything might help
• no worries. sent ur account info to my friend that works at riot. Enjoy the ban xD

At this point I would've loved to amend my report to include "Verbal Abuse" or "Hate Speech" (personally I think that shaming or implying mental illness is a form of hate speech, but that's another discussion entirely). Unfortunately, that's not possible; the button greys out and is no longer clickable after issuing a report.

My point is that some players are report-worthy during a match, some players are report-worthy after the match, and some players escalate from one to the next. Maybe the "Instant Feedback" shouldn't be quite so instant (wait to log or lock the report until after leaving the post match screen).

Thoughts?
