[Feature Request] I want to be able to use multiple arguments with slash commands.

When I'm writing a slash command, I can use the $ARGUMENTS placeholder to pass dynamic values to the slash command.

It would be very useful to be able to reference specific arguments at different places in my slash command prompt. Simple example: /custom-code-review "#123" "Architecture and security"

Your task is to review the pull request $ARGUMENTS[0], focusing only on $ARGUMENTS[1]
