XF 2.2 Different "avatar border radius" for threadlist v. postbit

[Live Free]

When viewing the list of threads in a forum I'm trying to design square stylized avatars like XF 1.5, but keep the circle avatars when viewing a thread. I know I can change the "avatar border radius" setting, but that changes it in both locations. Shouldn't be too hard with CSS, right? Has anyone accomplished this?

Hello,

Maybe this

[data-template="forum_view"] {
    .avatar {
        border-radius: 5px;
    }
}
