Time Tracking - Ability to enter non-specifc hours worked, copy cells

Please consider integrating a section in the time tracking boards where one can simply manually “add hours” to time worked with no time specified. Because the input method for manual time entered is quite time consuming, it would be nice to also be able to just put “2” into a secondary input method in the drop down under manual entering and 2 hours would be added without a specified time attached.

Also, is there no way to copy these “cells”? Sometimes we have pairs of people working on an item and they need to be duplicated, but we have to go in an manually reenter all the time with is SO time consuming.
