In the registers section ONLY counters and sensor responses have a response that can be associated with them.
Is there a reason why the flag table cannot have a response associated with it?
You can map other devices eg Cbus or KNX or Modbus addresses to Counters or Flags. For those devices where you want to trigger responses, you should map 6to counetrsFor devices that you do not need to use responses map to Flags
Flags are binary variables meant to show the status of external devices or internal conditions and should not need responses. Flags can also send commands and status to other devices eg yu can turn on or off cbus and knx and other devices by setting or clearing a flag
If you have an example of a situatiopn where you need a flag to trigger response, let us know. there may be a better way of acccomplishing it
