KNX ACK to some group address only

[Thomas]

Hi
Can I choose which group addresses are ACKed by LM?
The only option I've found is "ACK all group telegrams". But what does it mean?
- In case the checkbox is unchecked. Which group telegrams are ACKed? None?
- In case the checkbox is checked. Which group telegrams are ACKed?
    Really every?
Only these which are known for LM?
Only unfiltered?

Thank you for explanation.

Filter does not matter, either all or no group telegrams are ACK'ed.
