TouchBar: Activation of a button group for a specific time

I am not sure, maybe this has been asked and answered before but search did not retrieve anything.
I created a TB button group to control brightness and volume. I added a Close Group button to exit it.
Instead of actually having to push a button, would it be possible to close elements like buttons and button groups after a certain time?
I.e. if I want to change the brightness/volume, it is a fair assumption that after e.g. 10s I should be done and the button group could be closed.
Again, I am a new BTT user and might have missed that this already exists, in this case I would be thankful for a hint where to find it.
Otherwise, maybe a request for additional functionality :wink:

Long-time and happy BST use...
Keep up the good work!
