Ability to enter WHM as reseller from root WHM

As a Server Administrator, I want the ability to enter WHM as reseller from root WHM, so that I can perform actions through their user.

Similar to the ability to enter cPanel as an account from the list accounts page an option should be added to the reseller center to enter the WHM of a reseller directly so we no longer would have to enter the cPanel of an account under a reseller then enter WHM from the link at the bottom of the main cPanel page.

This is a feature that has been migrated over from the cPanel Forums. All previous comments and discussions concerning this feature can be located at:
