Yes, I'm aware I can see them in the log, as the second part of my question states:
"I've noticed that I can see them in the log and put together what's going on through there, but sometimes I get a capture and a state or switch has been set before the capture started, and I'd like to be able to definitively check its value."
My question was whether there's a way to watch them like with the Game Sync Monitor. There's a lot of spam in the log and it can be tedious to try and piece together what switch or state was set on what and when.
I'm pretty sure the answer is "no", but I know our debugging would be a lot easier sometimes if Wwise did have this feature, ESPECIALLY because of stuff changed prior to the start of the capture!
