You can make a style for your cells which supplies the following options:
CellProlog :> Module[{nb = EvaluationNotebook[]},
 SelectionMove[nb, All, EvaluationCell];
 SelectionMove[nb, All, CellGroup];
 SaveGrouping`save =
  Replace[NotebookRead[nb], {Cell[CellGroupData[___, cg_], ___] :> cg,
     Blank[] -> None}]]

CellEpilog:> Module[{nb = EvaluationNotebook[]},
  If[SaveGouping`save =!= None,
   SelectionMove[nb, All, EvaluationCell];
   SelectionMove[nb, All, CellGroup];
   NotebookWrite[nb, Replace[NotebookRead[nb],
     Cell[CellGroupData[a___, _], b___] :>
      Cell[CellGroupData[a, SaveGrouping`save], b]]]]]

This will make it so that mathematica remembers the current grouping
of a cell when you start evaluating it, and restores that grouping
after the evaluation is complete.
