A way to see "additional kanji" not present in the current learning mode?

I want to keep my settings to give me new kanji as soon as I burn them in WaniKani, but I'm also adding kanji in myself and these often aren't in the WK set. I have to go to settings, change the mode, review the kanji, go back to srttings, and swap it back to WK mode again. Shouldn't it be possible to find all the kanji in the app no matter which mode you're in? And just in case: you do continue reviewing kanji that aren't in the learning mode you're currently in, right?
