We’re there any attempts to standardize pitch accent in Japanese script?

In some other languages, there are systems to represent pitch textually in script. Though it is often overlooked, pitch is just as much a component of spoken words in Japanese as syllables are. There are many cases where words could be distinguished by pitch where they would otherwise be heteronyms. It doesn't seem that difficult to add in a script element to represent pitch (like diacritics of some kind). What are the most commonly accepted modern representations of pitch, and have there been historical attempts to represent pitch? What about when kana was first developed?

Edit: sorry for typo in title. Autocorrect
