Sunry and Utilities are actually populated by code coming from gnome-software...
the best will be to patch this code and do the same for yast I guess.
However, gnome-software isn't even installed on my system (I think it is not even installable due to conflict with Packagekit-branding-openSUSE). But Sundry and Utilities still show just fine.
