How to splinter general topics to more specific?

Dear moderators and admins, following the
forum-guidelines/5#Keep_It_Tidy
I would like to be able to split my general topic into segments as noted in the first topic post here (update: did start manually)
DeGROWTH follow-up from RIPE86 conference Now I do not see how to move sub-posts from it to new branched out topics as I do not have the level needed. Could you do that for me or grant me (temporary) permission?

Sorry to have to Ping you @Ulka , but at least you are informed :wink:
