If you really want to write it without disturbing srs, I think it would make most sense to write down the kanji right after your lesson/review. Either after each individual item, or all at once at the end (summary page).
You can add synonyms in your native language if you want.
I rely mostly on vocab. But for the items I have a harder time on I use the mnemonics.
You get one month free. Try the genki path alongside your book. Be careful of adding too many similar grammar points though as down the line you’ll feel like any number of possible grammar points could be the answer for a given question.
