How can we improve WHMCS?

Currently there is a very good feature, to allow admin to create admin users and assign permissions to them. However, when creating and managing additional administrators (Especially when creating temporary access admin accounts) someone might forget to disable the account after the thirdparty /temporary admin is done with the work they are supposed to do.

It would be great if while creating an account (or even already existing accounts, admin should be able to put a timer to disable the account. Maybe 1hr, 3hrs, 6hrs, 12hrs, 1day, No Limit etc. Will be more preferable if it is custom and not limited to a few preset value, so the admin can set timer according to the time the new user needs that access. After that time, then the account is disabled/deleted as per the admin settings when creating the account.

If the account is disabled then the admin can later open that account and enable it then setup a new timer.
