My b2evolution Version: 1.10.x

Hi there. In 1.9.0 and 2.1.0 there was the possibility to "beam" a comment or trackback directly to the antispam blacklist. In the comments list, there was a little "prohibition sign" icon just next to the comment or trackback entry heading.
Aaaah, [url=http://demo.b2evolution.net/stable/blogs/admin.php?ctrl=browse&show_past=1&show_future=1&tab=comments]here one can still see it[/url]. just beneath the URL of the comment.
If one clicked this icon, the comment or trackback was copied into the antispam interface.
Now I have to copy and paste manually, since this icon has gone... I miss that really much.
Does anyone remember the icon? Does anyone know if and how to get this back to life again?

Thanks in advance and kind regards, pgs
