I dont think theres a way, but if you go to https://www.anime-planet.com/ and go to the manga section theres a wider array of genres that sometimes are so specific that they almost are like tags, there you can choose multiple genres and well you get it, the manga with the things you selected show up ~yada yada~. Hope this was helpful! ヾ(❀╹◡╹)ﾉ~

On a similar note as user Lue said, try filtering categories at BakaUpdates first!

Thanks :)
