Revert accounts to package default via CLI

Hey. We have a number of cPanel servers where some accounts were kept on a plan but given different quotas. Is there a command we can run over the command line to sync all accounts to the package default. This also causes an issue when we try to update packages via uploading new setting to /var/cpanel/packages as only new accounts get the updated setting and old accounts stay on the old setting. For example if we increase bandwidth from 500mb to 1000mb all accounts on that package keep the old setting unless we make the edit via WHM
