This issue is basically just point #4 from this post.
You can be reasonably lenient with yourself in WK reviews and still hold yourself accountable for EN>JP reviews in an external tool. KameSame let’s you automatically import your WK items as you learn them. I’d be considered a borderline script abuser with my WK review process but I require myself to write out answers by hand in KameSame and verbally give the correct reading before submitting. If I mess anything up I manually fail myself. This system seems to be working great for me.
