How to get started on vocab without combing through a bunch of words?

I’ve been using Anki and making my own cards for quite a while, but I’ve recently been thinking to change to Bunpro vocab instead, since the cards make you use the words in context. But I’m a little overwhelmed because I’m going to have to comb through a lot of words that I already know. I’m thinking of starting with N3 because I’ve learned all the N5 and N4 words according to some other lists, but I might have missed some. I’ve also learned a couple hundred N3 words already (though I still don’t know most of them).

Do y’all have any suggestions on the most efficient way to do this? I’m aware of the “mark as mastered” button, but 1. I might have to navigate to it a bunch of times, and 2. I’m not really sure if I can confidently say I’ve “mastered” words (maybe ideally they’d be somewhere like in “seasoned”). Thanks for the help!

I’ve been using the “Set Default Progress Level” setting to achieve something like this, but I am interested in a way to go through and mark many words quickly.
Been on and off with learning for a few years now, and decided to recommit with bunpro during this sale. First time posting on the forums, so if anyone knows more I’d love to know:) どうぞよろしくお願いします
