Try again list

You can do something similar with userscripts. You could try using the double check script, which allows you to press a retry button after you answer. I use it in the same situations you do, where sometimes I accidentally rush through or make typos, and in those situations I can just retry and put in the correct answer. It’s easy to abuse, though, so try to only use it when you are confident you have the answer and it won’t affect your learning.

You can find the userscript here:

There are a lot more userscripts available to use, and this is a list containing a lot of useful ones you could use to customize WaniKani:
