One click clear local server DNS cache

An issue sometimes pops up when adding a new domain to an account on your server. You may have updated your A records and you may have checked for propagation on something like whatsmydns.net or google dig. To find that, yes, your new IP is showing and people are landing on the new IP address for the domain but you can't create an SSL cert as your server still has cached DNS info for the domain.
Just a clear server DNS cache button on the main backend would be amazing for this to streamline and speed up transfers where you want to limit downtime
