How to put a line comment for a multi-line command [duplicate]

I know how to write a multi-line command in a Bash script, but how can I add a comment for each line in a multiline command?

CommandName InputFiles      \ # This is the comment for the 1st line
            --option1 arg1  \ # This is the comment for the 2nd line
            --option2 arg2    # This is the comment for the 3nd line

But unfortunately, the comment after continuation character \ will break the command.
