Not that I know of, but I think you achieve it easily.

If you put a function on the idle-timer hook, then it will start to run
as soon as Emacs idles. If this function calls `sit-for' then it will
stall untill input arrives which is also when idle exits.

If you want a proper hook, you create a hook and have your idle function
call that hook.
