Disable user login for reseller-managed accounts

I have a reseller package at a web hosting company, which I use for hosting my clients' sites. I always login to my reseller account, and access my clients' accounts from there. My clients don't need access to DirectAdmin themselves.

My reseller account is properly secured with two-factor authentication, but I don't want to set this up for each client user.

Out of a security perspective, it would be nice if I could just disable login access to my clients' DirectAdmin users completely. In that case, I'd only need to keep my reseller account secured. Could such a feature be added?
