If I understand correctly, you are saying use a 32 channel input board + 8 channel relay board for each room I would like to control with "ALL ON" or "ALL OFF"? Thats a lot of unused inputs and panel space for such a simple function. Why not offer smaller i.e. 4,8,16 input versions of the switch input board?
for your case, use KC868-COL is best solution. COL with H32 relay board and many relay board with switch terminal board, cost almost same.
