Hi Paul,

Correct me if I'm wrong here, do you mean as I explain as screenshot here http://take.ms/ifueG ?
If yes, unfortunately it is not possible.
Perhaps, I've misunderstood you here, can you explain it a bit more detail with some screenshot?

Here is usage scenario:

Member starts a thread. Other members start replying. So far the thread has gotten 10 replies. The 7th reply is off topic but starts getting a lot of responses. Now the thread is up to 120 replies but almost all of them are in response to reply #7. So it makes sense that if you are "branching" that you branch off @ reply #7 and all of its responses that are off topic but on topic for Reply #7.

Hi Paul,

Yes I've understand the scenario correctly as above,unfortunately it is not possible currently.
