Selenium IDE - Random pause time

is it possible to make Selenium IDE wait random amount of time? Basically I need somehow simulate the human behavior, so it's not that obvious for the website (obviously it is suspicious if something clicks in precise time intervals on various links, right?). So I have set of rules which goes link after link, confirms by clicking on various links and all I need is to make random pauses between individual clicks. Is it doable in Selenium IDE, or is there some kind of workaround using Javascript + Selenium IDE? Thank you!
