Yes! After the name drawing is done, the group leader has two options available under the Group Settings menu. The "see who a person picked" menu option will take the group leader to a screen where all of the group members are listed. On that screen, the group leader can
select someone's name and see who that person picked in the name drawing.
Also under the group settings menu, the "See who picked a person" option will take the group leader to a screen where they can select
the name of a group member to find out who picked that person. This is sometimes used by group leaders to check who picked someone that hasn't received a gift for some reason.
So, group leaders can see anything they need to about the name drawing results, but try to only use your powers for good!
