at this moment i dont use new wp block editor still using classic html editor and at this moment were editing lots of articles in foreign language..default WordPress editor is something like this

if use italic tag on foreign word Encephalartos horridus it become like this <em>Encephalartos horridus</em> while what im trying to achieve is like this <i lang="la">Encephalartos horridus</i>

and since most the length article im currently working are to long (8k words),manually editing them one by one is just to tedious

is there any plugins or maybe a way to add custom tag in WordPress editor so i could just click them
