Copy & Paste Overwriting Modulation Instead of Adding

When using multiple channels and adding modulation data to channel 1 for example, then copying those data points to add to channel 2, instead of adding those points it is overwriting the channel one points. This is new. I have always been able to do this (copy, paste and change the channel to 2) Now the only way is to create a mod point outside of the other point a move it, one at a time. Even if you paste multiple points outside of the others and try to move that set over, it still replaces instead of adds.

I guess you talk about MIDI…

there is a setting that defines what happens with such events,
you can set this to merge or replace…

Where is that setting located? I have looked everywhere. There is no selection for paste and merge within the editor. Steinberg pooched this one. I have a feeling it has something to do with the new ramp selector.
