In order to pull a photo of an idol, you can type an idol's stage name, full name, alias, their group name, or group alias name after the prefix.
examples: %irene, %blackpink, %red velvet. You may also put an idol's stage name, full name, or alias after a group such as %red velvet irene.
You can use this with many idols to get a random one. %red velvet irene joy seulgi
This way, you will pull any of the idols as long as they are in that group.
To find out more, look at the GroupMembers category.
