without seeing the notebooks my guess would be that you might want to
do something like to tag the cells that you want to group and evaluate
together, then use NotebookFind to locate those tagged cells and then
SelectionEvaluate. Those steps could be combined into a function

evaluteCells[yourTags_String]:=(NotebookFind[nb, "yourTags", All,
CellTags];SelectionEvaluate[nb];)

where nb=EvalutionNotebook[]
