I don’t use Radio Userland any longer, but I found these instructions incredibly helpful, so here they are:
go to system.verbs.builtins.radio.data.systemUrls
add a name: kitNews
value: /system/kit/news
now go to system.verbs.builtins.radio.macros.adminMenu
scroll down to addCommand list
add the following: addCommand (“Kit News”,radio.data.systemUrls.kitNews)
save
