Show the full command when you start a Slash Command

In my case, using 8ball command you don't really know what the question really was. So i had to make the bot show the question before giving its answer. This wasnt a problem in old command since the user had to make a separate command. Why not just add the rest of the command, just like it shows when you click it? This might be helpful on other commands too. Like asking for images of something etc

Something like :
---deniscerri used /8ball question: "question"
BOT
<output>
