Add something automatically to the end of bash command

Question

I would like to know how to add something to the end of a specific bash command without having to type it out explicitly.

For example, I would like to be able to type:

$ mycommand argument

and the line will be submitted as:

$ mycommand argument &

I know how to set up an alias in my .bashrc (e.g. alias command="command -i") which will let me add non-positional arguments but I can't figure out how add something to the end.

You can can write a shell script, make it executable chmod +x filename and place it into one of the directories in the execution path (echo $PATH). This is more related to system administration. — Pinke Helga

You can declare a function instead of an alias if you need more power. — choroba

Does this concerns one (or a few) specific commands, or every possible command? — Ruud Helderman

A specific, pre-designated command. Updated question to be clearer. — otocan

Define a shell function.

mycommand () {
  command mycommand "$@" &
}

Thanks, this works. The key for me was the use of the of the command command, otherwise it wasn't interpreting the '&' correctly.
