New Notify Field On Updates Tab > Use Tab On Keyboard To Add User To Notify Field

With the Notify field that was introduced to the Updates tab with the R2 2018 release, I would like to be able to add users to the Notify field by typing part of their name, highlighting their name from the list and hitting tab on my keyboard to add them to the Notify field. Instead I have to use my mouse to click on their name.
The functionality I'm referring to still exists on the My Work > Updates > click the little people icon. This functionality makes it more efficient to add multiple users to be notified on an update.
