So the only work around I have discovered to remove a split across all lanes is to use the glue tool, and click on each Lane’s event before the split. So if I have 10 lanes, I have to click 10 times. I assume there must be a more efficient way to do this, as the Comp tool works across all lanes.
Seems like we have both found work arounds that take a bit of effort. It would be nice if the developers added a key modifier to the comp tool that deletes the split across all lanes, when you simply click on the split.
