[Haskell-cafe] Library function for map+append

During a small project I'm trying to develop a small application. It
becomes quite often that I need a function mapapp:
mapapp _  ap = ap
mapapp f (a:as) ap = f a : map f as ap
I tried hoogle to find such a function with no success. Is there any
function/functions built-in "standard" libraries that could easily
satisfy the functionality with the same or even better (?) efficiency?
(map f list) ++ append
would do the same as
mapapp f list append
but with less efficiency. Or am I wrong?
