Script for learning radicals/kanji outside of your level?

Is there a script that exists that lets you add a lesson for something outside of your level and add it to your review queue? A lot of the time, there is a useful word I want to learn right away but it’s many levels away, and learning it on my other SRS app isn’t as well rounded as WaniKani.

I don’t think there is any that let you skip ahead since it kinda go against the point of WK (having our learning path figured out for us so we just do the learning).

But you can look them up in WK system for the definitions on the site and then learn in other SRS maybe?
