/trigger descriptions for command suggestions

SInce /trigger is meant to be executed by the end user, it would be nice to add descriptive command suggestions.

By command suggestions I mean, when you type "/" above the console there would be a list of ["advancement","attribute",etc] you can Tab⭾ through

Imagine a scenario - You have installed a datapack that allows you to easily change common entity NBT's using "/trigger nbt set #". Lets say to make an item frame invisible you have to look at it and execute "/trigger nbt set 14" and the end user is like - what even is that supposed to mean?

It would be nice if you could "/scoreboard objectives modify nbt triggerdescription", so apon typing "/trigger nbt set", a command description would inform the player on what this trigger is supposed to be doing.
