Notes 9, embedded Sametime, buddy list, order of entries in buddy group

Have successfully migrated to IBM Notes 9 Social Edition and use the embedded Sametime,

I have a few groups for my contacts and within a group all contacts are automatically (by default) sorted by firstname. In my old external Sametime 8.5.2 I was able to change the order of my buddies as I like by simply dragging them to new positions.

Q: Is it really impossible in the new version to specifiy the order by myself?

Furthermore, is there a way to have a section for primary contacts (as in 8.5.2)?
