Add the ability to search by the user's name instead of just email address when utilizing "QUICK ADD USERS AND HOURS"

When using the "QUICK ADD USERS AND HOURS" it requires an email address instead of the name or email option that "ADD HOURS" gives. From what I have found, this is the only way to add hours for someone that did not respond to an ongoing (private) opportunity. And we don't allow our volunteers to add their own hours since we work with court-ordered community service workers.

We will sometimes have regular volunteers work with our construction team on shifts that are not offered to the public. I have an ongoing shift set up (FOR MANAGER USE ONLY - CONSTRUCTION) for these instances. If a user has not had hours added for that opportunity (and since I do not have it public for users to sign up themselves) I use the "QUICK ADD USERS AND HOURS" button to add those volunteer hours.

It adds extra steps when I have to go search the username for their email address (when if they already have a profile it should pop up as it does for "ADD AN HOUR ENTRY"). It would make things easier and save time for it to auto-populate if they already have an account when you search for their name.
