The only kinda workaround for now is to add a bunch of words to an anki card and set the interval of that card to over 21 days.
We will be adding a level feature tho, where you can select your current level and set a bunch of words as known.
When I switched to the extension I just marked all words in sentences I wanted to export as known (except the one that was new). Took about 1 week to get the extension pretty close to my level.
