html5 random rotation

Hello Arnan. I have a client that wants to run html5 ads within content. If I select a particular spot to run the ads, can it be set up to randomly load from one of a few ads that they want to provide? For example, if they have 4 different ads they want to use for the same location, can it randomly show one of the four with each page refresh? I plan on hiring your html5 service if this can be done.

Thanks!
