Page Restrictions: Add quicksearch to Enter user/group name(s)

I've been using Confluence every day for a year now and just now learned that you can select multiple users at the same time when applying page restrictions. Wow...what a time saver! For the past year I have been wasting a lot of time by:

1. clicking on "choose users" to open a new window
2. searching on the name of the user I want to add
3. checking the box next to the user in the search results
4. clicking on "Save as
5. repeating for every user I want to add

I wonder if other users out there have encountered the same waste of time without realising that they can add multiple users at the same time by typing in a comma-separated list of usernames into the Enter user/group name(s) box and clicking Add.

The problem as I see it is twofold:

1. The Enter user/group name(s) doesn't do quicksearch on names like it does in JIRA. This requires me to know the actual Confluence username
2. The Restrictions section of the page encourages me to click on the "Choose Users" tab (perhaps because it's prominent in the UI or perhaps because I don't know usernames). The problem with Choose Users is that it doesn't allow you to choose multiple users.

If we added quicksearch to the user Enter user/group names(s) field it would DRASTICALLY improve the experience.
