Automatically rebuild cache

Is there not a way to rebuild the cash for a list? I have members to my site and unfortunately the plugin that I am using to manage the members does not have a way to display a list of members so I am using “User Lists”. However, since I am not wanting to log into the site every day to update the cache so that new members show up on the list I was hooping there was a way to automate the list cache. Any help would be greatly appreciated.
