WP Toolkit fastcgi cache for multiple wordpress website

Hi, can WP Toolkit cache use for multiple wordpress website and purge individually? When I purge 1 website using nginx helper all cache purge. Is it possible to implement this function on WP Toolkit? I have been using this function for past few years modifying the configuration myself but it's still unavailable in aaPanel. I think it's due time implementing this function by default and it's not that complicated as I have already using it for long. I have told about this in the fastcgi setup page in here last time. If you need my help then I can provide you the configuration need to modify. So you know what need to implement to achieve this function by default. It will be really helpful for people who is not very comfortable modifying configuration and even will make life easy for everyone. Thanks
