    Description

      If there are too many regions in one overlapped group (by default, more than 10), hbck currently doesn't merge them since it takes time.
      In this case, we can sideline some regions in the group and break the overlapping to fix the inconsistency. Later on, sidelined regions can be bulk loaded manually.
