5 card Omaha calculator

Hi everyone, I've been playing 5 card Omaha online for about half a year and I've realised that my understanding of odds there is a bit off. So I've tried to find the odds calculator and all I am able to find is the 4 card one.

Does anyone know any calculator (preferably easy to use one, such as cardplayer.com has for the 4 card Omaha)?
